The organism blood vessel state measurement equipment which can detect relatively quick change in regard to the image pickup which relates to the inside specified probe of the plural probes is offered. The electrocardiogram test section possessing 26 which measures the electrocardiogram of subject 12 and the respective plural ultrasonic oscillators, as it is constituted, plural ultrasonic array probes A and B which scan that blood vessel 36 by the fact that the ultra wave is output vis-a-vis the blood vessel 36 which becomes the object from those plural ultrasonic oscillators, it has with C, same period doing in the corrugated signal in the electrocardiogram which is measured those plural ultrasonic array probes A and B, among C at least in regard to one ultrasonic array probe, by the aforementioned electrocardiogram test section 26 it scans the blood vessel 36 which becomes the object, in the other ultrasonic array probesRegarding, same period doing in the aforementioned corrugated signal, from the fact that it is something which scans the blood vessel 36 which becomes the aforementioned object at higher frequency than the ultrasonic array probe which scans, observing to the picture which corresponds to the inside each probe of the plural probes, it is possible to scan frequently.複数の探触子のうち所定の探触子に係る撮像に関して比較的急速な変化を検出し得る生体血管状態測定装置を提供する。被験者12の心電図を測定する心電図測定部26と、それぞれ複数の超音波振動子を有して構成され、それら複数の超音波振動子から対象となる血管36に対して超音波を出力することでその血管36の走査を行う複数の超音波アレイ探触子A、B、Cとを、備え、それら複数の超音波アレイ探触子A、B、Cのうち少なくとも1つの超音波アレイ探触子に関して、前記心電図測定部26により測定される心電図における波形信号に同期して対象となる血管36の走査を行うと共に、その他の超音波アレイ探触子に関して、前記波形信号に同期して走査を行う超音波アレイ探触子よりも高頻度で前記対象となる血管36の走査を行うものであることから、複数の探触子のうち何れかの探触子に対応する画像に注目して頻繁に走査を行うことができる。
