PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic apparatus or the like which implements an improvement in SNR and an increase in spatial resolution.SOLUTION: An ultrasonic diagnostic apparatus acquires, for each scanning line, a plurality of reception signals corresponding to a plurality of ultrasonic beams by performing a plurality of times of ultrasonic transmission/reception on the same scanning line, detects a phase difference between temporally adjacent reception signals of a plurality of reception signals on the each scanning line at each sampling point on the each scanning line, performs correction processing including at least time delay correction for at least one of a plurality of reception signals for the each scanning line based on the phase difference at each sampling point on the each scanning line, adds, for the each scanning line, the plurality of reception signals including a reception signal subjected to the correction processing, and generates a first image from the reception signals added for the each scanning line.COPYRIGHT: (C)2014,JPO&INPIT【課題】SNRの改善と空間分解能の向上とを実現した超音波診断装置等を提供すること。【解決手段】同一走査線上にて複数回の超音波送受信を行うことで、複数の超音波ビームに対応する複数の受信信号を走査線毎に取得し、走査線毎の複数の受信信号のうち時間的に隣接する受信信号間の位相差を、各走査線上の各サンプル点において検出し、各走査線上の各サンプル点における前記位相差に基づいて、走査線毎の複数の受信信号の少なくとも一つに対し、少なくとも時間遅延補正を含む補正処理を実行し、補正処理が行われた受信信号を含む複数の受信信号を走査線毎に加算し、走査線毎に加算された受信信号から第1の画像を生成する超音波診断装置である。【選択図】図5
