Universal Deep Beamformer for Variable Rate Ultrasound Imaging

7 Jan 2019Shujaat KhanJaeyoung HuhJong Chul Ye

Ultrasound (US) imaging is based on the time-reversal principle, in which individual channel RF measurements are back-propagated and accumulated to form an image after applying specific delays. While this time reversal is usually implemented as a delay-and-sum (DAS) beamformer, the image quality quickly degrades as the number of measurement channels decreases... (read more)
