波と−して用いることを特徴とする超音波ドプラ装置。An ultrasonic pulse beam is irradiated into the object based on the excitation signal obtained by modulating the carrier wave with a transmission repetition signal obtained by dividing the frequency of the oscillation pulse oscillated from the main oscillator. Based on the reflected echo, each part of the object is detected. An ultrasonic Doppler device that detects motion as a Doppler signal has a frequency multiplier circuit that multiplies the frequency of the oscillation pulse during division by an arbitrary integer multiple, and converts the oscillation pulse multiplied by the arbitrary integer multiple into a carrier wave. An ultrasonic Doppler device characterized in that it is used as a.
