Pipelined sampled-delay focusing CMOS implementation for ultrasonic digital beamforming

, 2003
The real-time ultrasonic imaging system can be achieved using a digital beamforming (DBF) method. The critical part of the DBF is the real-time sampled-delay focusing (SDF) which requires a large number of memories (FIFO) to store the scanned ...
