Special Issue Information

Dear Colleagues,

I am excited to share with you an opportunity to contribute to a Special Issue of Electronics titled "Signal and Image Processing for Theranostic Ultrasound". As a Guest Editor for this Special Issue, I aim to highlight innovative research at the intersection of signal and image processing and theranostic ultrasound, a field poised to revolutionize personalized medicine.

About the Special Issue:

Theranostic ultrasound, which combines diagnostic imaging with therapeutic interventions, is transforming healthcare by enabling precise imaging and targeted treatments. This Special Issue focuses on advanced signal and image processing techniques that enhance the capabilities of theranostic ultrasound, aiming to address challenges such as image quality, therapeutic precision, and real-time guidance.

Topics of interest include, but are not limited to, the following:

  • Advanced ultrasound imaging techniques;
  • Signal processing for improved image quality;
  • Integration of diagnostic and therapeutic ultrasound;
  • Development of ultrasound contrast agents;
  • Real-time image processing for guided therapy;
  • Clinical case studies of theranostic ultrasound.

This Special Issue will provide a platform to share groundbreaking methodologies, applications, and insights that advance theranostic ultrasound research and practice.

Your work in this field could significantly enhance the Special Issue’s impact and foster collaboration among researchers working on related challenges. Submissions to this Special Issue will be rigorously peer-reviewed and published in Electronics, ensuring visibility and engagement with a broad, interdisciplinary audience.

I believe your expertise would make a valuable contribution to this Special Issue, and I would be delighted to discuss potential topics if you are interested. Please feel free to reach out to me with any questions or ideas you might have.

A circular array transducer with high frequency and small aperture size is highly desired for intravascular ultrasound (IVUS) imaging application. With the breakthrough of array transducer techniques, high-frequency circular array transducers with the advantages of high frame rate and high resolution have been developed and manufactured. Focusing on the development of a matched high-frequency imaging algorithms, this study introduces apodization functions into 55 MHz circular-array IVUS imaging, proposes a circular-array-specific apodization model, and breaks the lateral-resolution limit inherent to conventional delay-and-sum (DAS) beamforming. In the study, three typical algorithms—synthetic aperture (SA), apodized synthetic aperture (ASA), and sparse synthetic aperture (SSA)—are investigated in order to well achieve an effective imaging result for our newly derived circular array transducer with 55 MHz. In the scatterer’s simulation, at a depth of 1.5 mm, the ASA algorithm improves the lateral resolution from 260 μm for conventional SA to 175 μm (a 33% enhancement), while tripling the frame rate. Meanwhile, SSA maintains a resolution of 300 μm and reduces the data volume by 50%, laying the groundwork for real-time 3D imaging. Further phantom imaging testing shows that the SA algorithm has the best imaging effect on regional defects. The ASA algorithm has the best imaging effect on point defects while improving the imaging frame rate. This study provides insights and a foundation for optimizing circular-array intravascular ultrasound imaging, the proposed ASA model can be directly ported to existing 40–60 MHz circular-array IVUS systems, offering a new route for accurate early-plaque identification.
