Abstract
A color Doppler-type ultrasonic apparatus is provided in which an ultrasonic pulse beam is transmitted, from a transducer, along a tomographic plane to be scanned toward an object containing a moving target. A Doppler shift frequency is detected on the basis of an echoed ultrasonic pulse beam for every sampling volume of the tomographic plane, and an image of the tomographic plane is displayed. The apparatus comprises an element for calculating movement information including a direction and a magnitude of velocity of the moving target for each of the sampling volumes on the basis of the detected Doppler shift frequency, an element for specifying a reference direction on the image of the tomographic plane, an element for forming data of a color sample showing a directional relation between the calculated directions and the reference direction, an element for creating data for color display of the calculated velocity for each of the sampling volumes on the basis of the directional relation; and an element for color-displaying at least the created data for color display together with the formed data of color sample.
