Short-Acquisition Contrast-Free Super-Resolution Microvascular Imaging in Rabbit Kidney
A contrast-free super-resolution microvascular imaging technique using high-frequency ultrafast ultrasound and nonlinear beamforming achieves 22.2 μm resolution at 8 frames/s with 125 ms acquisition in a rabbit kidney model, showing three-fold improvement over power Doppler.
