ULTRASONIC IMAGING DEVICE

摘要

Provided is an ultrasound imaging apparatus which can compensate deterioration in the image quality resulting from heterogeneity of a test object medium. A reception beamformer 108 performs synthesizing after performing phasing processing of a signal received by an ultrasound element array 105 for each of two or more steering directions. The two or more steering directions are instructed by a steering direction instruction unit 112. The two or more steering directions include two directions each of which forms predetermined angles on the right and left with respect to a direction of a reception focal point along the ultrasound element array in an array direction. The predetermined angles are preferably null angles.

1. An ultrasound imaging apparatus comprising:
an ultrasound element array that includes multiple ultrasound elements arrayed along a predetermined direction; a reception beamformer that performs phasing of a signal received by the ultrasound element array; and an image processing unit that uses an phasing output which is output by the reception beamformer and generates image data, wherein the reception beamformer includes a phasing synthesizing unit which performs synthesizing after performing phasing processing of the signal received by the ultrasound element array for each of two or more steering directions and a steering direction instruction unit which sets the two or more steering directions to the phasing synthesizing unit, and wherein the two or more steering directions include at least two directions other than a direction of a reception focal point.
