Introduction
Exploring the physical characteristics and mechanisms of the interior of the planet and its interactions with various natural phenomena is the focus of Earth science's field of geophysics.It involves using physics concepts to examine Earth's composition, structure, and dynamics.Seismic waves, electromagnetic fields, gravity, and magnetic fields are just a few of the techniques that geophysicists employ to learn more about Earth's interior and its different layers [1].Fundamentally, geophysics acts as a link between the Earth sciences and the physical sciences.Geophysics provides essential insights below and beyond our line of sight.Geophysicists have revealed the stratified nature of Earth's interior, from the molten core to the solid crust, by painstakingly analyzing seismic waves from earthquakes [2].Maps of subsurface features have been produced using gravity and magnetic surveys, assisting resource exploration and providing a better knowledge of tectonic plate movements.Additionally, geophysical techniques allow us to explore the exteriors and innards of other celestial bodies in addition to our planet [3].
Geophysics has a significant role in many parts of contemporary life.Natural resource exploration is one of its major contributions [4].Geophysical technologies support sustainable resource management and economic growth by locating mineral deposits, groundwater reservoirs, and hydrocarbon reserves [5,6].Additionally, geophysics is essential for hazard reduction.Scientists can better forecast earthquakes, tsunamis, and volcanic eruptions by keeping an eye on seismic activity, ground deformations, and volcanic processes [7].This will protect communities and infrastructure [6].
Our understanding of Earth's dynamic history is also based on geophysics.Geophysicists have contributed to the understanding of the history of Earth's magnetic field reversals and the migration of continents over millions of years by examining the magnetic characteristics of rocks [8].Geophysical methods also aid environmental research by allowing for the monitoring of land subsidence brought on by human activity, the evaluation of soil and water contamination, and the tracking of groundwater movement [9,10].Geophysics has expanded outside its conventional fields in recent years, finding use in unexpected fields.Notably, its concepts have been applied in the field of health sciences [11,12], where methods like MRI use principles of strong magnetic fields, which had their origins in geophysics, to provide remarkably detailed images of internal human bodily structures [13,14].
In essence, geophysics is an invaluable tool for understanding the inner workings of Earth and solving the mysteries that exist underneath its surface.Natural resource management, emergency preparedness, environmental protection, and scientific research are all impacted by it [15].The traditional uses of geophysics have been summarized in Table 1.

Seismology
The study of seismic waves produced by earthquakes or other sources is known as seismology.These waves reveal details about the composition of Earth's inner layers and the characteristics of the materials that constitute them.[16] Gravity and magnetic surveys Geophysicists can locate subsurface features like faults, mineral deposits, and even underground water reservoirs by detecting fluctuations in Earth's gravitational and magnetic fields. [17]

Electromagnetic methods
To determine the electrical conductivity and other characteristics of the subsurface, electromagnetic techniques such as magneto-telluric examine fluctuations in Earth's electromagnetic field. [18]

Geodesy
The goal of geodesy is to precisely measure the gravitational field, shape, and rotation of Earth.For mapping, navigation, and a general understanding of Earth dynamics, this information is essential.[19] Geothermal studies To investigate the distribution of heat on Earth and the possibility of geothermal energy production, geophysicists employ a variety of techniques.[20] Natural resources exploration By identifying abnormalities in the subsurface, geophysics is essential in locating important resources like oil, gas, minerals, and groundwater.[8] Volcanology Researchers can keep track of and better understand the mechanisms underlying volcanic eruptions, reducing the risks associated with them by examining seismic activity, ground deformation, and other geophysical indicators.[21] Table 1.Cont.

Tectonics and plate movements
Our understanding of tectonic plate movement, the forces that propel it, and the geological events that emerge from it, such as earthquakes and mountain development, is aided by geophysics. [22] Environmental studies To research how human activity affects the planet, geophysical techniques are used, including monitoring changes in the surface and subsurface of the planet as a result of things like groundwater extraction, land subsidence, and more.[23] In the twenty-first century, numerous multidisciplinary studies have grown significantly, with one fascinating and revolutionary partnership arising between the historically separate domains of geophysics and health sciences.This confluence shows an increasing understanding that the ideas and methods produced in one area can be imaginatively used to address problems in another, frequently leading to ground-breaking answers that go beyond the bounds of traditional disciplines.Due to their mutual desire to discover unknown domains, geophysics and health sciences have recently begun to intersect significantly.Utilizing imaging technologies has allowed geophysics, historically linked with exploring Earth's interior, and health sciences, which study human physiology, to collaborate more effectively.These tools, honed in the field of geophysics, have been redesigned to reveal the inside architecture and functioning of the human body in unparalleled detail [12].
The use of methods like magnetic resonance imaging (MRI) is an illustration of the growing collaboration between geophysics and the health sciences.Strong magnetic fields are used in MRI to provide precise images of soft tissues and organs.MRI was first designed to map geological features beneath the surface of Earth.Through non-invasive visualization of interior anatomy, early illness identification, and surgical intervention guidance, this interdisciplinary synergy has revolutionized diagnostic medicine [24].
Additionally, the similarities in characteristics between biological tissues and geological formations have inspired creative uses [25].For instance, the geophysical technique known as electrical impedance tomography (EIT), which is used to map differences in subsurface electrical conductivity, has been reimagined to capture changes in electrical conductivity inside the human body.This method shows the power of multidisciplinary borrowing by showing promise in monitoring lung function and finding anomalies.Moreover, the fusion of geophysics and health sciences solves typical computational issues.Both disciplines struggle with huge datasets and complex data processing requirements.For the correct and effective reconstruction of medical pictures, computational geophysical techniques like tomography and inversion techniques are being used [26].Simultaneously, advances in the interpretation of geophysical data are being driven by the complex algorithms created in the health sciences, such as ML for medical picture analysis [27].Figure 1 shows that diagnostic and imaging techniques in health sciences share fundamental principles with geophysics methods [12,[27][28][29].
The continued partnership between geophysics and the health sciences emphasizes how transformational interdisciplinary research may be.It involves encouraging a creative interchange of ideas, processes, and insights rather than merely translating techniques from one discipline to another.This convergence is expanding the parameters of scientific inquiry and fostering a cross-disciplinary problem-solving culture.We can anticipate new diagnostic tools, improved treatment approaches, and a deeper knowledge of both Earth's secrets and human well-being as geophysics and health sciences continue to collaborate.The review article focuses on: • The principles and operating processes behind various geophysical techniques used in healthcare.

•
Geophysical techniques that can be adapted and used in imaging techniques.• The incorporation of artificial intelligence (AI) and machine learning (ML) for technological advancement in geophysics-driven medical imaging.The continued partnership between geophysics and the health sciences emphasizes how transformational interdisciplinary research may be.It involves encouraging a creative interchange of ideas, processes, and insights rather than merely translating techniques from one discipline to another.This convergence is expanding the parameters of scientific inquiry and fostering a cross-disciplinary problem-solving culture.We can anticipate new diagnostic tools, improved treatment approaches, and a deeper knowledge of both Earth's secrets and human well-being as geophysics and health sciences continue to collaborate.The review article focuses on:

The field of health sciences has been explored through geophysical techniques, which have historically been used to reveal the secrets of Earth's subsurface.These methods have been cleverly repurposed to see inside the complex landscapes of the human body.They were originally developed to decipher geological features and uncover hidden treasures.A transformational synergy has developed by fusing the seemingly unrelated fields of geophysics and health, providing non-invasive methods for imaging medical problems, tracking physiological processes, and solving medical mysteries [12].Several techniques currently used in health sciences have their principles derived from geophysics and have been listed in Table 2. [32] Ultrasound Imaging High-frequency sound waves are used in ultrasound procedures to produce images of soft tissues and organs.These techniques were inspired by seismic approaches.
For real-time visualization, it is commonly utilized in obstetrics, cardiology, and other medical disciplines. [33]

Elastography
Elastography techniques, which were adopted from seismic technologies, measure the movement of mechanical waves across the body to determine the stiffness of the tissue.These data are useful for identifying anomalies and evaluating tissue health. [34] Computerized Tomography (CT) CT scans, which employ X-rays to create cross-sectional images of the body, are not directly geophysical methods.There are similarities between the reconstruction algorithms used in CT imaging and the tomographic methods used in geophysics.
[ 35,36] Positron Emission Tomography (PET) PET imaging picks up injected positron-emitting radionuclides.Although not explicitly a geophysics technique, the concepts of gamma-ray detection are comparable to those of the gamma-ray spectrometry used in geophysics.[37,38] Functional MRI (fMRI) fMRI is an advancement above conventional MRI in that it maps brain activity by monitoring changes in blood flow and oxygenation.This method sheds light on the cognitive functions and functional connectivity of the brain. [39] Diffusion Tensor Imaging (DTI) DTI, which is based on the diffusion of water molecules, is a technique used in neuroimaging to show the neuronal connections and pathways in the brain.Diffusion-based geophysical techniques serve as the basis for this strategy.
[40] NMR Spectroscopy NMR spectroscopy, which is derived from NMR methods used to study molecular structures and is utilized in medical settings to examine biological molecules, is an area of study in molecular biology and medicine. [41] Near-Infrared Spectroscopy (NIRS) The NIRS technique evaluates the tissues' near-infrared light absorption, which was first applied in geophysics to examine mineral composition.It is used in the health sciences to measure brain activity, monitor vital signs in neonatal care, and evaluate tissue oxygenation. [42]

Photoacoustic Imaging
Photoacoustic imaging combines optical and ultrasonic approaches and is inspired by seismic methods.By sensing the acoustic waves that tissues emit when they absorb laser-generated light, it creates images.High-resolution imaging of tumors, blood arteries, and other structures is made possible by this method. [43]

Fluorescence Imaging
Despite not being a direct geophysics tool, fluorescence imaging is analogous to how fluorescence is used in geology.Fluorescent molecules are employed to mark certain cells in medical settings, facilitating cellular imaging, cancer diagnosis, and therapeutic development. [44]

Terahertz Imaging
Terahertz imaging uses terahertz radiation, which was first applied to astronomy and atmospheric research, to see inside biological tissues.This method may be used to evaluate tissue characteristics and detect skin malignancies. [45]

Biomechanical Analysis
The ideas of analyzing material qualities and deformation in geophysics have influenced biomechanical analysis in the health sciences; however, this is not a specific geophysics technique.Biomechanical analysis includes determining how organs and tissues react to mechanical forces, assisting in the creation of orthotics and prostheses, and comprehending how people move. [46] The opportunity for interdisciplinary study between geophysical methods and health sciences is enormous and growing all the time.Scientists are discovering novel approaches to improve medical diagnoses, solve physiological puzzles, and advance our understanding of human health and well-being as they investigate how adaptable these methods are [12].

Electromagnetic Imaging Method
Electromagnetic methods in geophysics use electromagnetic waves to collect data on the characteristics of Earth's subsurface.These techniques use electromagnetic field interactions with materials to infer information on the underlying composition, conductivity, and structures of Earth [47].The foundation of electromagnetic techniques is the idea that various materials respond differently to electromagnetic waves with different frequencies.Geophysicists can generate representations or models of the subsurface by monitoring these responses and assisting in geological exploration, resource discovery, and environmental studies [48].
Faraday's law of electromagnetic induction and Ampère's law, which states that electric currents produce magnetic fields, serve as the foundations of electromagnetic survey methodologies [49].Faraday's law, which can be expressed in its most basic form as "a changing magnetic field will induce an EMF," asserts that the electromotive force (EMF) in a closed circuit is proportional to the rate of change of magnetic flux through the circuit [50].
The magnetic flux (∅B) crossing a closed loop is mathematically expressed as [51]: where Ň is the outward pointing normal vector for the loop and → B is the magnetic flux density, which is proportional to the magnetic field in free space.
Faraday's law relates the magnetic flux through the surface bordered by the loop to the induced EMF in the loop [52]: The current I' flowing in the wire is related to the EMF through Ohm's law: where R is the electrical resistance of the circuit.Some of the common electromagnetic methods in geophysics have been listed in Table 3, and the integration of electromagnetic methods in health sciences has been displayed in Figure 3.
It has been a revolutionary convergence of disciplines when electromagnetic techniques from geophysics have been used in the health sciences.These techniques, which were first created to investigate Earth's subsurface, have been imaginatively repurposed to reveal complex bodily landscapes [12].These methods have found use in physiological research, neuroscience, and medical diagnostics by taking advantage of interactions be-tween electromagnetic waves and biological tissues, and the common methods are listed in Table 4.

Electromagnetic Induction
A transmitter coil is used to produce a magnetic field that changes over time.
Electrical currents are induced in conductive subsurface materials as a result.
Receiver coils at the surface detect the secondary magnetic fields that are produced as a result of these induced currents.

Faraday's law of electromagnetic induction
Groundwater exploration, mineral resource identification Where E is the induced electrical field, σ is electrical conductivity, and ∂B ∂t is the rate of change of the magnetic field.[48,49] Ground Penetrating Radar (GPR) Short electromagnetic pulses are released into the ground using GPR.The travel period of these pulses is measured after they reflect off subsurface contacts.Information about the depth and characteristics of subsurface features can be gleaned from the timing of the reflected waves.
EM wave reflection at material boundaries Archaeology, environmental studies, detecting buried objects Where t is the time taken for the signal to travel to the subsurface and back, ϑ is the wave speed, and d is the depth.[53,54]

Magnetotellurics (MT)
Earth's electromagnetic field naturally varies owing to interactions with the sun and other celestial bodies, as measured by MT.A variety of frequencies are used to record these fluctuations.Earth's impedance response sheds light on changes in subsurface resistivity.
The penetration of electromagnetic waves is influenced by the conductivity of Earth.

Mapping subsurface structures, understanding geological formations
The ratio of the vertical electric field (E z ) to the horizontal magnetic field (H y ) is used to calculate the impedance (Z) Z = Ez Hy [20,55] 14, x FOR PEER REVIEW 8 of 26  Where E is the induced electri-  Detecting anomalies in the brain and assisting with pre-surgical planning for diseases like epilepsy [57,58] Functional Electrical Stimulation (FES) [59,60] FES (FES), a medical treatment used in the health sciences, uses regulated electrical currents to help paralyzed or weak muscles regain or improve their function.Electrical impulses are delivered to specific muscles or nerves during FES, prompting them to contract and produce movement.For people with diseases like spinal cord injuries, strokes, or neuromuscular abnormalities, this method is especially helpful.Although FES is not directly related to geophysics, its basic principles have some loose similarities to geophysical ideas.The fundamentals of electrical currents and their effects on materials are fundamental to both fields and electrical methods are utilized in geophysics to examine subsurface conductivity variations.FES works by implanting electrodes near the target location or placing electrodes on the skin to provide regulated electrical pulses to muscles or nerves.These electrical impulses cause muscle contractions, enabling people with paralysis or weak muscles to carry out practical motions like standing or walking.

Cardiac Electrophysiology Mapping
Cardiac electrophysiology mapping is a sophisticated method used to visualize and examine the electrical activity of the heart.This approach assists in recognizing irregular heart rhythms (arrhythmias), locating their causes, and directing medical procedures like catheter ablation.Cardiac electrophysiology mapping entails mapping the electrical signals of the heart in great detail to diagnose and treat a variety of cardiac diseases.Cardiac electrophysiology mapping and geophysical methods can be broadly compared by understanding how electrical currents spread across a medium, although this is not directly related to geophysics.

Seismic Imaging in Medical Applications
Seismic waves, which are produced by controlled sources like explosions or vibrators and recorded by sensors called geophones or seismometers, are used in seismic imaging in the context of geophysics [66].These waves interact with diverse geological features and formations as they move through Earth's subsurface.The created images of the subsurface, which reveal important details about its composition, structure, and the presence of resources like oil, gas, and minerals, are created from the recorded seismic data.The principles of wave reflection, refraction, and transmission underlie seismic imaging [67].
Seismic waves experience variations in speed and direction when they encounter subsurface boundaries that have different qualities (such as density, elasticity, and rock type).Some of the waves are reflected back to the surface as a result of these modifications, and the sensors capture these reflections.Geophysicists can determine the features of subsurface layers and formations by examining the arrival times and amplitudes of these reflected waves [68].Seismic profiles or sections are produced by combining data from various geophones or seismometers in seismic imaging.With the help of these profiles, you can see strata, faults, folds, and other geological characteristics in two dimensions [69].Data are collected from different angles using more sophisticated techniques, such as 3D seismic imaging, to provide three-dimensional images that offer even more insight into subsurface structures.
In the seismic method, the seismic velocity model can be estimated to image some part of Earth's subsurface given the condition that the modeled travel time matches with the observed seismic travel times, and the expression is given by [70]: For the estimation of velocity, the difference between the observed and modeled travel times is minimized and the equation is given by: ∆t = D∆s where ∆t = travel time difference vector, D = ray distance value matrix, and S = slowness vector.
Seismic imaging, which has historically been used to study Earth's subsurface, has developed a distinctive and ground-breaking use in the field of medical sciences.Techniques for seismic imaging have been inventively repurposed from geophysics to depict the complex dynamics and features of the human body.Seismic imaging, used in the medical sciences, provides a non-invasive and in-depth image of inside tissues and organs by utilizing the principles of wave propagation and reflection [71].This interdisciplinary convergence has paved the path for new diagnostic capabilities, allowing healthcare providers to access previously unavailable insights.A deeper comprehension of human anatomy, better illness detection, and more precise treatment planning are all made possible by seismic imaging, which continues to close the gap between geophysics and medicine.This synergy between two seemingly unrelated scientific fields is truly remarkable [12].
Figure 4 illustrates the application of seismic reflection techniques in diagnostic imaging, including ultrasound imaging, elastography, ARFI, and shear-wave dispersion ultrasound vibrometer [12,67,72].Moreover, the different techniques that have been derived from seismic images in geophysics for health sciences have been listed in Table 5.

Description Working Applications Refs. Ultrasound Imaging
Ultrasound imaging is a non-invasive, safe, and extensively used medical imaging technique that employs high-frequency sound waves (ultrasound) to produce real-time images of the body's internal components.While geophysics studies Earth's subsurface with seismic waves, ultrasonography visualizes internal structures with sound waves.To reveal concealed information, both areas rely on wave interactions, reflection, and imaging techniques.
The notion of sound wave reflection underpins ultrasound imaging.A transducer sends ultrasonic waves into the body that bounce off tissues and organs to create echoes.These echoes are received by the transducer and converted into electrical impulses.A computer then processes these impulses to generate visuals that are displayed on a monitor.

Elastography
Elastography is a type of medical imaging that assesses the stiffness or elasticity of tissues.It offers information about the mechanical properties of tissues, assisting in the identification of anomalies and assessing circumstances that affect tissue stiffness.
In geophysics, seismic waves move through the subsurface of Earth and interact with various rock layers to disclose details about their characteristics.Like this, elastography interacts with tissues using mechanical waves, assesses their reaction, and reveals information about the characteristics of the tissues.
Elastography is the process of applying mechanical forces to tissues and monitoring how they respond.Elastography techniques include shearwave elastography, strain elastography, and magnetic resonance elastography.Shear-wave elastography is commonly used to create shear waves within tissues using ultrasound or other mechanical techniques.The speed of these shear waves as they propagate through the tissue is measured.Shear waves are transmitted faster by stiffer tissues than by softer ones.

MRI and Geophysics
The basic concepts of magnetic fields and signal detection are fundamental to both geophysics and MRI.They both use the interaction between magnetic fields and matter to extract useful information, despite having differing functions.By examining how various materials react to magnetic signals, geophysicists may investigate Earth's subsurface and learn about its structures and characteristics.In contrast, MRI uses radiofrequency pulses and strong magnetic fields to provide precise images of the human body's internal structures that highlight variations in tissue composition.Although their scales and goals are different, the fact that they both use magnetic interactions to probe matter highlights how closely related they are [81,82].
NMR is a concept that MRI technology uses in the field of medical imaging [83].It entails exposing the human body to a strong magnetic field that is frequently tens of thousands of times stronger than the magnetic field of Earth.The hydrogen atoms in the body's tissues have their nuclear spins aligned by this powerful magnetic field.The hydrogen nuclei absorb energy when a radiofrequency pulse is applied, and as they realign themselves, they begin to transmit signals.These "resonances" or signals are picked up by sensors and utilized to build extremely precise pictures of the insides of organs, blood arteries, and even the complicated networks of the brain [84,85].
The mutual reliance on powerful magnetic fields is the most overt sign of the relationship between MRI and geophysical principles.Both fields are aware of the special characteristics of magnetic materials and how they react to outside magnetic fields.Geophysics uses measurements of fluctuations in Earth's magnetic field to deduce subsurface geological formations.Like this, MRI uses the interaction of powerful magnetic fields with tissue hydrogen nuclei to produce the signals that make up medical imaging.The applications and results, however, differ greatly [86].Understanding Earth's past, finding important resources, and foreseeing geological dangers are the objectives of geophysics [87].In contrast, MRI focuses on non-invasively visualizing the human body's internal structure to detect disorders, track the effectiveness of treatment, and direct surgical procedures.In addition to demonstrating the adaptability of magnetic interactions, the relationship between MRI and geophysical principles also emphasizes the interdisciplinary aspect of scientific advancement.It emphasizes how ideas from one field can be imaginatively modified to address problems in another.Strong magnetic fields are used in MRI and geophysics, which is an example of how research may go beyond preconceived bounds and benefit both human health and our comprehension of the natural world.The field of medical diagnostics has undergone a profound transformation because of improvements in MRI techniques, which have made it possible to more precisely and thoroughly visualize interior organs and bodily processes [13].These developments have had a substantial impact on how different medical illnesses are diagnosed, enabling earlier detection, more accurate characterization, and better patient outcomes.Several advanced techniques have been listed in Table 6.

Spectroscopic Imaging
This method determines the chemical composition of tissues, allowing for metabolic evaluations.Spectroscopic imaging improves tumor characterization in oncology by distinguishing between malignant and healthy tissue.[96,97] 3D and 4D Imaging Modern imaging methods provide real-time, four-dimensional and three-dimensional views of organs and structures.This makes it easier to visualize dynamic movements, intricate anatomical linkages, and cardiac activity. [85] Ultra-High Field MRI Greater spatial and temporal resolution is made possible by stronger magnetic fields (7T and higher).The visualization of small structures, such as blood arteries, joints, and the brain, is enhanced by ultra-high field MRI, which enhances diagnostic precision.[83,84] Quantitative MRI By measuring particular tissue characteristics like T1 and T2 relaxation periods, this method makes it easier to distinguish between healthy and sick tissues.It helps determine the severity of diseases including multiple sclerosis and liver fibrosis.
[98] AI Integration AI-driven methods help automate image interpretation, improve image quality, and shorten scan times.AI tools help radiologists spot problems and boost their level of diagnostic assurance.
[ 99,100] By providing innovative methods for detecting a variety of ailments, from neurological problems to cardiovascular diseases, oncology, and beyond, MRI techniques promise to make even bigger contributions to medical science as they continue to advance.The future of healthcare is extremely promising when personalized medication, new imaging techniques, and AI-driven methods are combined [101].

Geophysical Data Analysis in the Health Sciences
Geophysics has many applications in various fields, including in the diagnostic sphere of the medical sector [96,97], and some of the focal points are energy efficiency and sustainable development [98,99].
One key area where geophysical data analysis is making an impact in medical contexts is the analysis of biomedical signals.Techniques such as signal processing, time-series analysis, and spectral analysis, which are commonly used in geophysics to analyze seismic, electromagnetic, and other data, have been adapted to analyze medical signals like ECGs, EEGs, and even molecular data from gene expression studies [102].These methods help identify patterns, anomalies, and trends within complex medical signals, aiding in the diagnosis of cardiac arrhythmias, neurological disorders, and genetic diseases [103].
The study of biomedical signals is one important area where geophysical data analysis has an impact in medical contexts.The analysis of medical signals like electrocardiograms ECGs, EEGs, and even molecular data from gene expression studies is now possible using methods like signal processing, time-series analysis, and spectral analysis, which are frequently used in geophysics to analyze seismic, electromagnetic, and other data.These techniques assist in the detection of cardiac arrhythmias, neurological illnesses, and genetic diseases by locating patterns, abnormalities, and trends within complex medical data [104,105].
In addition, medical imaging uses geophysical inversion techniques, which are utilized to retrieve subsurface properties from observed data.These techniques are used in medical imaging to recreate images of internal structures from a variety of modalities, including CT, MRI, and ultrasound [106].The inversion techniques contribute to more precise and detailed medical imaging by enhancing spatial resolution, reducing artifacts, and improving image quality [107].
The examination of biological processes at the molecular and cellular level using geophysical principles in the science of biophysics is another interesting application.Examples include the use of methods like NMR spectroscopy, which was initially created to study the behavior of atomic nuclei in Earth materials, to examine the structure and dynamics of biological molecules like proteins and nucleic acids.This clarifies molecular connections, assisting in the development of new drugs and the comprehension of disease mechanisms [107][108][109].
The similarities in the mathematical and statistical techniques needed to glean useful information from large, complex datasets underlie the relationship between geophysical data analysis and medical situations.The algorithms, models, and tools created in geophysics are being repurposed to analyze medical data as data-driven approaches become more common in medicine, opening up new perspectives and opportunities [110,111].The accuracy of data analysis depends on reliable procedures, cutting-edge algorithms, and experts in both geophysics and medical imaging.Erroneous conclusions can result from errors or misinterpretations, which may result in missed opportunities or poor medical decisions.The significance of proper data analysis increases as technology develops because the complexity of data necessitates advanced approaches to extract insightful information [112,113].
The analysis and interpretation of complicated medical data have benefited from the use of computational tools that were initially created for processing geophysical data.These methods take advantage of the similarities between data analysis, signal processing, and image reconstruction to provide insights that lead to more precise diagnoses, individualized therapies, and better patient care [114].In the field of health sciences, the following geophysical analysis procedures are now in use:

•
Signal Processing: ECG, EEGs, EEGs, and even functional MRI data are treated as medical signals using signal processing techniques utilized in geophysics, including filtering, noise reduction, and Fourier analysis.These methods aid in pattern recognition, abnormality quantification, and information extraction from noisy data [115,116].

•
Image Reconstruction: Medical imaging modalities like CT and MRI are developed from geophysical data inversion methods, which are used to rebuild subsurface structures.These techniques produce more realistic reconstructions of anatomical features by improving image quality, lowering artifacts, and boosting spatial resolution [117].

•
Data Fusion: Medical data fusion uses methods for integrating various geophysical information to provide a full perspective of subsurface features.Combining data from various imaging modalities (such as MRI and PET) in medical imaging allows for a more thorough understanding of the interior organs and their activities [118,119].

•
ML and AI: Medical imaging uses tomographic techniques to recreate precise images of organs and tissues.Tomographic techniques are frequently utilized in geophysics to build 3D images of subsurface objects.Examples include X-ray CT and PET scans, where cross-sectional images are produced using information from various angles [120][121][122][123]. • Tomographic Imaging: Medical imaging uses tomographic techniques to recreate precise images of organs and tissues.Tomographic techniques are frequently utilized in geophysics to build 3D images of subsurface objects.Examples include X-ray CT and PET scans, where cross-sectional images are produced using information from various angles [124].

•
Inverse Problem Solving: Techniques for inverse problem-solving are used to recover data from imperfect or indirect measurements in both geophysics and medicine.This aids in the discovery of subsurface features in geophysics and the reconstruction of images from sparse data in medicine, such as in magnetic resonance spectroscopy (MRS) for the investigation of metabolic processes [122].

•
Quantitative Analysis: To measure qualities such as tissue density and blood flow in medical imaging, computational approaches that quantify variables like density, composition, and electrical conductivity in geophysics are modified [125,126].

•
Image Registration: To register medical pictures from various periods or modalities, geophysical techniques that align and match multiple datasets are used.This aids in monitoring illness development, evaluating therapy effectiveness, and directing interventions [127,128].
The application of geophysical computational methods in the field of medicine emphasizes the interdisciplinary aspect of contemporary science.These methods not only improve the accuracy of medical data analysis but also offer a fresh viewpoint on medical problems [129].Medical researchers can make use of the developments achieved in geophysics by modifying and extending computational tools to push the boundaries of medical diagnostics, treatment approaches, and our comprehension of the vast complexity of the human body.This interdisciplinary cooperation enhances diagnostic precision, showcasing the broader implications of technology transfer for advancements in medical research and patient care [128,129].

Artificial Intelligence (AI) and Machine Learning (ML) Applications
AI and ML have significantly transformed medical imaging by advancing data analysis across various modalities (Table 7).In diagnostic radiology, AI algorithms enhance the interpretation of X-rays, CT scans, and MRIs, accelerating the identification of abnormalities and streamlining diagnostics.Computer-aided diagnosis (CAD) systems, powered by AI, play a crucial role in mammography, aiding early detection of breast cancer by analyzing mammograms and assisting radiologists in making more precise diagnoses.The application of AI extends to cardiac imaging, where ML is utilized to detect cardiovascular diseases and abnormalities in heart function through the analysis of echocardiograms and cardiac MRIs.In pathology, ML contributes to image analysis, supporting pathologists in diagnosing diseases, particularly cancer, by examining tissue samples and identifying specific markers or abnormalities [130].
Neuroimaging benefits from AI, which aids in mapping brain activity, identifying neurological disorders, and studying brain connectivity using functional MRI (fMRI) and diffusion tensor imaging (DTI).Ophthalmology leverages AI for the analysis of retinal images, enabling the detection and monitoring of conditions like diabetic retinopathy [131].Positron emission tomography (PET) imaging sees AI analysis for cancer diagnosis and staging, enhancing the identification and characterization of tumor activity.Ultrasound imaging benefits from ML applications, improving accuracy in fetal imaging, organ recognition, and abnormality detection across various medical specialties.Quantitative image analysis, facilitated by AI, provides objective measurements of features such as tumor size and density, contributing to cancer research and treatment monitoring [132,133].
The integration of medical imaging data with genomic information is achieved through AI, enabling a comprehensive understanding of diseases and supporting personalized treatment strategies.These diverse applications underscore the transformative potential of AI and ML in enhancing diagnostic precision, efficiency, and patient outcomes in the dynamic field of medical imaging.Staying informed about ongoing research is crucial to keeping pace with advancements in this rapidly evolving domain.ML and AI are related but distinct fields, and their separation is meaningful in the context of health sciences.ML, a subset of AI, focuses on creating algorithms that enable computers to perform tasks without explicit programming, learning and improving from data or experience [134].
In health sciences, ML is extensively applied for predictive modeling, classification, and pattern recognition, contributing to tasks such as diagnosing diseases, predicting patient outcomes, and identifying risk factors.On the other hand, AI is a broader concept encompassing various technologies beyond ML, including natural language processing, robotics, and expert systems.In healthcare, AI extends beyond ML to include reasoning, problem-solving, and decision-making capabilities, providing a comprehensive approach to improving diagnostics, treatment plans, and healthcare management.The separation of ML and AI allows for a nuanced understanding, acknowledging ML's specific role in learning from data and AI's broader spectrum of technologies that contribute to intelligent decision making in health sciences [135].

Linear Regression
Application involves predicting patient outcomes based on clinical parameters, such as age, blood pressure, and cholesterol levels.In clinical trials, linear regression aids in analyzing the relationship between treatment dosage and response.The method is also employed for assessing risk factors associated with specific health conditions and modeling disease progression over time.Public health studies benefit from linear regression to understand how environmental factors impact population health.

Logistic Regression
Logistic regression can be utilized to assess the probability of a patient developing a particular disease based on various risk factors such as age, genetic predisposition, and lifestyle choices.This method is instrumental in risk assessment and enables healthcare professionals to identify significant predictors for targeted interventions.Logistic regression is also employed in clinical research, analyzing factors influencing treatment success or failure.

Decision Tree and Random Forest
Decision trees, being intuitive and easy to interpret, are often applied to predict outcomes such as disease presence or treatment response.For instance, a decision tree might be constructed to assess the likelihood of a patient developing a specific condition based on various medical parameters.Random forests, which are ensembles of decision trees, offer enhanced predictive performance and robustness.In health sciences, random forests find applications in scenarios where complex relationships among multiple variables influence health outcomes.For example, in genomics, random forests can be used to identify genetic markers associated with certain diseases by analyzing large datasets.
