Wiener beamforming and the coherence factor in ultrasound imaging
The coherence factor (CF) is used for aberration correction and sidelobe suppression in ultrasound imaging. Unfortunately, it suffers from artifacts when the SNR is low. We show how the CF can be interpreted as an implementation of the Wiener postfilter for a delay-and-sum beamformer. In addition, w...
