摘要： Pulses of an ultrasonic wave beam are emitted into a body at a predetermined repetition period. Echo pulses of the ultrasonic wave beam are received via a plurality of different channels. Each of the received pulses is converted simultaneously into corresponding electric signals of the respective channels. A time-dependent change in a variation between the electric signals of the respective channels is derived. A component of a speed of moving matter within the body in a predetermined direction is calculated on the basis of the derived time-dependent change. The moving matter causes the echo pulses. The predetermined direction is perpendicular to a direction of travel of the ultrasonic wave beam pulses.

摘要： An ultrasonic Doppler blood flowmeter measures the velocity of blood flow at an arbitrary position of the body of a subject by making use of Doppler shift of an ultrasonic echo signal. The echo signal including Doppler shift from the blood flow of the body is detected in phase on the basis of standard reference signal, and the distance to an intended position is extracted from the phase detected signal and is integrated, and the direct-current component or ultralow frequency component of the Doppler shift signal obtained from the integrator is fed back negatively to the integrator. As a result, the echo signal components of the body tissues are removed, and the frequency of blood flow only can be analyzed, so that an accurate blood flow information may be obtained.
