Abstract:
1. An ultrasonic diagnostic imaging system comprising: a probe including an array of transducer elements; a transmit beamformer, coupled to the array of transducer elements, and operable to transmit a beam insonifying a plurality of laterally spaced line positions; a multiline receive beamformer, coupled to the array of transducer elements, which is operable to produce a plurality of receive lines at the line positions in response to one transmit beam; a multiline combining circuit, responsive to a plurality of receive lines which are to be combined for a common line position and produced by the multiline receive beamformer in response to a plurality of transmit beams, which is operable to delay each receive line with a delay related to the lateral location of each receive line in relation to its transmit beam location and to nonlinearly combine the plurality of delayed receive lines to produce image data; and a display which produces an image utilizing the image data.
