Abstract
Official abstract text for this publication.
An ultrasonic diagnostic apparatus includes: a first reference beam generating unit generating a first reference beam from DAS signals calculated in an N-th frame; a second reference beam generating unit generating a second reference beam from a DAS signal calculated in an (N−1)-th frame, the DAS signal calculated in the N-th frame, and another DAS signal calculated in an (N+1)-th frame; an attenuation coefficient calculating unit calculating, based on the first reference beam and the second reference beam, an attenuation coefficient to be multiplied by the DAS signals calculated in the N-th frame; and a beamforming unit generating and providing a beamformed signal generated for a reference scan line in the N-th frame by multiplying a DAS signal calculated in the N-th frame by the attenuation coefficient.
First claim
Opening claim text (preview).
The invention claimed is: 1. An ultrasonic diagnostic apparatus comprising a beamformer which generates beamformed signals, each corresponding to one of scan lines for generating an ultrasound image, from echo signals generated from ultrasound signals bounced off a subject and received by receiving elements, wherein the beamformer includes: a delay-and-sum (DAS) unit configured, for each of frames, to (i) determine one of the scan lines, in a sorting order determined in a give…
