<p>An ultrasonic pulse Doppler apparatus comprising an ultrasonic probe (14) for transmitting ultrasonic beam into an object and receives the echoes from the object, a first processing circuit (10a, 10c) for processing the echoes received by the probe (14) to form data of a B scan tomogram, a first monitor (13a) for displaying the B scan tomogram, beam mark setting circuit (11) for setting a plurality of beam marks (3a,...) on the B scan tomogram, measuring point setting circuit (12A) for setting a plurality of blood flow measuring points (2a,...) on each of the beam marks, beam mark selecting circuit (SW1) for selecting any one of the plurality of beam marks, measuring point selecting circuit (SW2 to SW10) for selecting any one of the plurality of blood flow measuring points on the selected beam mark, a second processing circuit (10b, 10d) for processing the echoes received by said probe (14) to form a signal of a blood flow velocity at the selected measuring point, a second monitor (13b) for displaying the blood flow velocity at the selected measuring point, and modulating circuit (12B) for distinguishing the selected measuring point on the selected beam mark from other measuring points.</p> |
