Regardless of the depth of the suffering inspection body, the ultrasonic diagnostic device which obtains proper distortion information is offered. Through the aforementioned ultrasonic probe to the ultrasonic probe and add pressure to organism organization of the suffering inspection body compressed expedient and the organism organization which send and receive the ultra wave with the suffering inspection bodies distortion picture formation expedient and the distortion which are warped on the basis of the distortion distribution which was requested and the reflected echo signal which occurs from transmission expedient and the suffering inspection body which transmit the ultra wave through the aforementioned ultrasonic probe, with distortion information operational expedient and the said distortion information operational expedient which request the distortion distribution of organism organization on the basis of the frame data of the pair where the acquisition time which is received by reception expedient and the said reception expedient which are received differs form the pictureHaving with the indicatory expedient which indicates the picture, it provided the distortion distribution revision expedient which revises distortion distribution with the distortion distribution revision function which is set in compliance with the pressure condition due to compressed expedient in the ultrasonic diagnostic device which becomes. Depending, it can obtain proper distortion information regardless of the depth of the suffering inspection body.被検体の深度に関わらず、適正な歪み情報を得る超音波診断装置を提供する。被検体との間で超音波を送受する超音波探触子と、被検体の生体組織に圧迫を加える加圧手段と、生体組織に前記超音波探触子を介して超音波を送信する送信手段と、被検体から発生する反射エコー信号を前記超音波探触子を介して受信する受信手段と、該受信手段により受信された取得時刻が異なる一対のフレームデータに基づいて生体組織の歪み分布を求める歪み情報演算手段と、該歪み情報演算手段により求めた歪み分布に基づいて歪み画像を生成する歪み画像生成手段と、歪み画像を表示する表示手段とを備えてなる超音波診断装置において、加圧手段による圧迫条件に応じて設定された歪み分布補正関数により、歪み分布を補正する歪み分布補正手段を設けた。よって、被検体の深度に関わらず適正な歪み情報を得ることができる。
