Method and apparatus for high-frame-rate high-resolution ultrasonic image data acquisition

摘要

Data for high-frame-rate high-resolution (i.e., low f-number) ultrasonic imaging are acquired by a technique that involves transmitting multiple physically separated beams simultaneously and acquiring imaging data for more than one scan line during receive. Spatial apodization (36) is used to influence the transmit beamformation (26) and to form two controlled and focused spatially separate beams with a single firing of the transducer array elements and without use of additional timing electronics.
