Title:
STEERING POSSIBLE DOPPLER TRANSDUCER PROBE
Document Type and Number:
Japanese Patent JPS61179138
Kind Code:
A
Abstract:
An ultrasonic diagnostic probe is provided which performs simultaneous ultrasonic imaging and Doppler flow measurement. The Doppler transducer (32) is mounted for rotation by a mechanical assembly, which permits the Doppler beam (130) to be steered during imaging to the point in the body where a flow measurement is to be taken. As the Doppler transducer (32) is rotated, a variable impedance device (80) within the probe is adjusted in correspondence with the transducer rotation so as to provide an indication signal of the direction in which the Doppler beam (130) is being directed.
