ABSTRACT:
An ultrasonic measurement apparatus provided with a probe connected to a Doppler flow meter, and a movement detecting probe, both of which probes are mounted on an actuator, which is driven by a synthesizer which is adapted to repeatedly reproduce a set waveform synchronously with the cardiac motion of a living body, whereby the distance between the probes and a region of interest in the interior of the living body is kept substantially constant irrespective of the movement, which occurs due to the cardiac motion, of the region of interest to enable a measurement signal from the region of interest to be constantly obtained. The movement detecting probe is connected to a M-mode imaging apparatus to thereby make it possible that a M-mode image thereon be monitored to determine whether a suitable waveform is generated by the synthesizer.
