Row-column (RC) matrix probes can yield 3-Dvolumetric imaging using a number of receiving elements similarto traditional linear arrays for commercial scanners. Some doubtshave, however, been raised on the B-mode image quality ofRC probes. It is hypot

Delay-and-sum (DAS) beamforming is unable to identify individual scatterers when their density is so high that their point spread functions overlap. This paper proposes a convolutional neural network (CNN)-based method to detect and localize high-den

Row-column (RC) arrays have the potential to yield full 3-D ultrasound imaging with a greatly reduced number of elements compared to fully populated arrays. They, however, have several challenges due to their special geometry. This review article sum

Capacitive micromachined ultrasonic transducers (CMUTs) have a nonlinear relationship between the applied voltage and the emitted signal, which is detrimental to conventional contrast enhanced ultrasound (CEUS) techniques. Instead, a three-pulse ampl

The search for improved resolution in super-resolution ultrasound (SRUS) imaging leads to larger ultrasound arrays and smaller elements. A current large row-column addressed (RCA) array spans $\approx 21\times 21\ \text{mm}^{2}$ with $190 +190$ eleme
