Pixel-reassignment in Ultrasound Imaging [PDF]
Appl. Phys. Lett. 119, 123701 (2021), 2021 We present an adaptation of the pixel-reassignment technique from confocal fluorescent microscopy to coherent ultrasound imaging. The method, Ultrasound Pixel-Reassignment (UPR), provides a resolution and signal to noise (SNR) improvement in ultrasound imaging by computationally reassigning off-focus signals acquired using traditional plane-wave ...
