Far-field compressive ultrasound beamforming
Nikunj Khetan, Jerome Mertz
We present a compressive beamforming method for coherent plane-wave compounding (CPWC) ultrasound imaging based on a far-field decomposition of the received radiofrequency (RF) dat…
Plane-wave compounding with adaptive joint coherence factor weighting
Nikunj Khetan, Jerome Mertz
Coherent Plane Wave Compounding (CPWC) is widely used for ultrasound imaging. This technique involves sending plane waves into a sample at different transmit angles and recording t…
Ultrasound differential phase contrast using backscattering and the memory effect
Timothy D. Weber, Nikunj Khetan, Ruohui Yang +1
We describe a simple and fast technique to perform ultrasound differential phase contrast (DPC) imaging in arbitrarily thick scattering media. Though configured in a reflection geo…
Speed-of-sound imaging by differential phase contrast with angular compounding
Nikunj Khetan, Timothy Weber, Jerome Mertz
We describe a technique to reveal speed-of-sound (SoS) variations within an echogenic sample. The technique uses the same receive data as standard pulse-echo imaging based on plane…
