Super-Resolution Ultrasound Imaging utilizing Random Interference and Joint Image Reconstruction

Abstract: In ultrasound, wave interference is an undesirable effect that degrades the resolution of the images. We have recently shown that a wavefront of random interference can be used to reconstruct high-resolution ultrasound images. In this study, we further improve the resolution of interference-based ultrasound imaging by proposing a joint image reconstruction scheme. The proposed reconstruction scheme utilizes RF signals from all elements of the sensor array in a joint optimization problem to directly reconstruct final high-resolution images. By jointly processing array signals, we made significant improvements in the ultrasound resolution. The results of the simulation and experimental studies show that the proposed method achieves a superior contrast and image resolution. Furthermore, we share our simulation codes as an open-source repository in support of reproducible research.
