Adaptive B mode ultrasound image processor

摘要

The B mode processor (54) has a signal envelope detector providing input to a logarithmic data compression stage (48a) and to a low pass filter (52a). The outputs are fed to a signal edge shaping stage (50) and to a further data compression stage (48b). Signals are combined in an adaptive weighting circuit and the output is directed to an anti-aliasing filter (52b).
