Abstract
An ultrasonic imaging apparatus comprised of an ultrasonic transducer array that transmits ultrasonic waves to a subject under examination and receives ultrasonic waves reflected from within the subject under examination and a scan controller that controls the transducer array to transmit/receive the ultrasonic waves in the same direction repeatedly and to change the transmitting/receiving direction of the ultrasonic waves in a sectional plane of the subject under examination. The apparatus also includes a detector that detects Doppler shifted frequency data at a plurality of points in the sectional plane from a received signal by the transducer array and a display that displays blood flow of the subject. A memory stores a plurality of types of patterns having a maximum velocity, a minimum velocity and a number of frames per unit time of blood flow to be detected in various combinations. A selector selects a pattern from the types of patterns, and a controller sets a parameter for the number of times the ultrasonic waves are repeatedly transmitted/received, a parameter for a repetition period during which the ultrasonic waves are repeatedly transmitted/received, and a parameter for the number of times the direction of transmission/reception of the ultrasonic waves is changed in the scanning plane. The controller also controls the scan controller and the detector in accordance with the set parameters so as to implement the pattern selected by the selector.
