Abstract

See full text

In performing aperture synthesis according to an ultrasound imaging apparatus, the amount of spatial change of amplification factors of phasing signals at respective receive phasing points are reduced, and a high-quality image is obtained. In a receive beamformer that generates an inter-transmission weight in accordance with a phasing range, and performs aperture synthesis processing, the inter-transmission weight being generated is applied to the receive phasing points within the phasing range obtained through transmission and reception, and the inter-transmission synthesis is performed. The inter-transmission weight is generated in such a manner that a variation form of the amplification factor between adjacent receive phasing points is smoothed and a difference of the amplification factor is reduced, as to each receive phasing point after the inter-transmission synthesis is performed.
