Adaptive ultrasound beamforming
Summary: We present a method, called Joint Coherence Factor (JCF) adaptive weighting, to separately evaluate the quality of each spatio-angular signal contribution in coherent plane-wave compounding (CPWC), and to weight each accordingly upon beamforming. By suppressing low quality signal in CPWC at the level of individual spatio-angular signal contributions, we effectively suppress incoherent clutter and noise, resulting in improved image quality. Conventional ultrasound imaging is inherently noisy. Our technique of noise and clutter suppression compares favorably with other techniques when applied to soft tissue imaging, providing a direction for improved medical ultrasound imaging.
