Background,Motivation and Objective The synthetic aperture imaging(SAI) method in medical ultrasonic imaging is widely known for improving image quality by synthesizing the transmit focusing at all depths.As in the bidirectional pixel-based focusing(BiPBF;M.H.Bae et al.,IEEE TUFFC,vol.47,2000),SAI can be combined with receiving dynamic focusing,or as in the synthetic aperture sequential BF(SASB;J.Kortbek et al.,IUS 2008),SAI can be used with fixed-point receive focusing(FPRF).SASB has a significant advantage over BiPBF that its hardware complexity can be greatly reduced.

Background,Motivation and Objective In medical ultrasound imaging,a constant sound speed(e.g.,1540 m/s) is typically used for receive beamforming.However,due to inhomogeneity in soft tissues,the propa
