PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic device that obtains, at a high speed, an electronic scanning surface perpendicular to machine moving direction, and generates a pseudo three-dimensional image of high quality and high density.SOLUTION: The ultrasonic diagnostic device includes: a probe that includes a plurality of ultrasonic transducers arranged in a first direction and configured to transmit an ultrasonic wave and receive a reflection wave, and performs ultrasonic electronic scanning by transmitting and receiving ultrasonic waves sequentially from one side to the other side a mover for moving the probe, on an object to be measured, continuously in a second direction crossing at an angle that is not perpendicular to the first direction and an image calculation section for generating, based on an echo signal output from the probe, a tomographic image data of the object to be measured in a third direction perpendicular to a plane including the first direction and the second direction. One end of the probe where ultrasonic waves are transmitted or received first is inclined toward the probe moving direction.COPYRIGHT: (C)2012,JPO&INPIT【課題】機械移動方向に対して垂直な電子走査面を高速で取得し、高精度かつ高品質な擬似3次元画像を生成することが可能な超音波診断装置を提供する。【解決手段】第1の方向に配列され超音波を送信し反射波を受信する複数の超音波振動子を含み、超音波の送受信を一方から他方の端部へと順に行うことで超音波の電子走査を行う探触子と、探触子を、測定対象の上で、第1の方向と垂直ではない角度で交差する第2の方向に連続的に移動させる移動手段と、探触子から出力されるエコー信号に基づいて第1の方向と第2の方向を含む平面に垂直な第3の方向における測定対象の断層像データを生成する画像演算部を有し、探触子は、超音波の送受信が先に行われる側の端部が、移動される向きに対して前側になるように傾斜していることを特徴とする超音波診断装置を用いる。【選択図】図5
