Ultrasonic diagnosis apparatus

An ultrasonic diagnosis apparatus comprising:

• scanning means for scanning a subject to be examined while transmitting and receiving an ultrasound pulse to and from the subject;
• means for obtaining velocity information about a moving element within the subject based on reception signals acquired by the scanning performed by the scanning means;
• display image producing means for producing an image to be displayed indicative of a state of pulsation on the basis of the velocity information;
• and
• means for controlling the display image producing means so that display of the pulsation is switched on or off on the basis of the velocity information.

An ultrasonic diagnosis apparatus comprising:

• scanning means for three-dimensionally scanning one section of a subject to be examined a plurality of times corresponding to one heartbeat while transmitting and receiving an ultrasound pulse to and from the subject;
• means for obtaining in sequence velocities of a moving element within the subject based on reception signals obtained three-dimensionally by the scanning means;
• processing means for computing a reference velocity based on the plurality of velocities obtained from during a predetermined period of time and correcting each of the velocities of the moving element using the reference velocity so that data of the corrected velocities is obtained;
• and
• displaying means for displaying at least a three-dimensional image based on the data so that the image is updated a plurality of times during the predetermined period of time.
