This invention, the signal reception expedient which receives the ultrasonic reflected wave which was irradiated from ultrasonic lighting expedient and the said ultrasonic lighting expedient in the medical application ultrasonic device which irradiates ultrasonic pulse vis-a-vis the remedy or inspection region, and the signal record expedient which records the reception signal (memory), and the relative expedient which compares with the record signal and the said reception signal (the comparison operation element) is the medical application ultrasonic device which it has. Depending upon the device of this invention, reproducibility it becomes possible well to verify appropriate remedy or inspection position.本発明は、治療又は検査部位に対して超音波パルスを照射する医療用超音波装置において、超音波照射手段、該超音波照射手段から照射した超音波の反射波を受信する信号受信手段、受信信号を記録する信号記録手段(メモリ)、及び記録信号と該受信信号との比較を行う比較手段(比較演算素子)を備える医療用超音波装置である。本発明の装置によって、適切な治療又は検査位置を再現性よく確認することが可能となる。
