Abstract
Medical ultrasound imaging has unique requirements regarding spatial and amplitude resolution, near-field focusing, wide bandwidth, and real-time operation. Only recently has Capon beamforming been adapted to this. We give examples of images of point targets, cysts, and regions dominated by speckle and discuss how subaperture smoothing, diagonal loading and range/time averaging must be balanced for best performance.Keywords
