Super-resolution ultrasound mostly uses image-based methods for the localization of single scatterers. These methods are largely based on the center of mass (COM) calculation. Sharpness-based localization is an alternative to COM for scatterer locali

In this work the accuracy of row-column tensor velocity imaging, i.e., 3-D vector flow imaging in 3-D space over time, is quantified on complex, clinically relevant flow. The quantification is achieved by transferring flow simulated using computation

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

Current super resolution imaging is conducted using ultrasound contrast agents, where a sparse distribution ofbubbles must be employed to separate individual targets. Thesparse targets make the acquisition time long in the range of1 to 10 minutes, an
