SPARSE CONVOLUTIONAL BEAMFORMING FOR ULTRASOUND IMAGING

机译:稀疏卷积波束形成的超声成像

摘要

A method comprising: receiving from multiple transducers respective signals comprising reflections of a transmitted signal from a target; processing said signals to derive a beamformed signal, based, at least in part, on: (i) computing a specified value associated with each of said signals, (ii) performing a convolution on all said specified values, (iii) calculating a weighted sum of the results of said convolution, to derive said beamformed signal; and reconstructing an image of said target, based on said beamformed signal.
