Special Issue Information

Dear Colleagues,

Biomedical microwave imaging and sensing have emerged as promising technologies in the field of healthcare. Leveraging the properties of microwaves, these modalities offer non-invasive and radiation-free alternatives for imaging and monitoring biological tissues. Building upon the principles of radar technology, biomedical microwave imaging utilizes low-power microwaves to penetrate tissues and generate detailed images. It has shown potential in various applications, including breast cancer detection, brain imaging, and monitoring physiological parameters. These techniques have the advantage of being cost-effective, portable, and safe.

The next steps towards the clinical use of biomedical microwave imaging and sensing involve addressing several challenges. Firstly, further advancements in imaging algorithms and machine learning techniques are needed to enhance image quality, improve resolution, and reduce artifacts. Secondly, validation studies and clinical trials are essential to establish the efficacy and reliability of microwave imaging and sensing in real-world healthcare settings. Moreover, the miniaturization and optimization of hardware components, such as antennas and sensors, will contribute to the development of compact and user-friendly devices suitable for clinical use. Finally, regulatory approvals are crucial to ensure widespread adoption and integration into routine clinical practice and into existing medical systems. By addressing these steps, these techniques hold great potential for revolutionizing medical diagnostics and monitoring, leading to improved patient outcomes and personalized healthcare.

Angiography is a very informative method for physicians such as cardiologists, neurologists and neuroscientists. The current modalities experience some shortages, e.g., ultrasound is very operator dependent. The computerized tomography (CT) and magnetic resonance (MR) angiography are very expensive and near infrared spectroscopy cannot capture the deep arteries. Microwave technology has the potential to address some of these issues while compromising between operator dependency, cost, speed, penetration depth and resolution. This paper studies the feasibility of microwave signals for monitoring of arteries. To this aim, a homogenous phantom mimicking body tissue is built. Four elastic tubes simulate arteries and a mechanical system creates pulsations in these arteries. A multiple input multiple output (MIMO) array of ultra-wideband (UWB) transmitters and receivers illuminates the phantom and captures the reflected signals over the desired observation time period. Since we are only interested in the imaging of dynamic parts, i.e., arteries, the static clutters can be suppressed easily by background subtraction method. To obtain a fast image of arteries, which are pulsating with the heartbeat rate, we calculate the Fourier transform of each channel of the MIMO system over the observation time and apply delay and sum (DAS) beamforming method on the heartbeat rate aligned spectral component. The results show that the lateral and longitudinal images and motion mode (M-mode) time series of different points of phantom have the potential to be used for diagnosis. Full article
