PROBLEM TO BE SOLVED: To perform a parallel simultaneous reception method with a high frame rate.SOLUTION: An ultrasonic diagnostic apparatus of the embodiment includes a transmission part and a reception part. The transmission part transmits ultrasonic waves. The reception part, using digital signals of reflection waves of the transmitted ultrasonic waves, when forming the respective reflection wave data of a plurality of scanning lines for the portion of the simultaneous reception numbers, performs the processing of forming reflection wave data in the sample points of the respective scanning lines situated in the same depth along the azimuth direction, while changing the position in the depth direction.COPYRIGHT: (C)2014,JPO&INPIT【課題】並列同時受信法を高いフレームレートで行なうこと。【解決手段】実施形態の超音波診断装置は、送信部と、受信部とを備える。送信部は、超音波を送信させる。受信部は、送信された超音波の反射波のデジタル信号を用いて、同時受信数分の複数の走査線それぞれの反射波データを生成する際、方位方向に沿って同じ深さに位置する各走査線のサンプル点の反射波データを生成する処理を、深さ方向の位置を変更しながら行なう。【選択図】図1
