Abstract
There is provided an ultrasonic diagnosis apparatus in which a region containing an organ of an object being examined is diagnosed by means of ultrasonic beams, the organ being in motion, the apparatus comprising: an element for scanning the region by the ultrasonic beams to obtain ultrasonic echo signals having Doppler shift; an element for calculating movement velocities every sampling volume on the basis of the ultrasonic echo signals; and an element for displaying in color the movement velocities.
Claims15
An ultrasonic diagnosis apparatus in which a tissue in a cross section of an object being examined is imaged by means of an ultrasonic beam, the tissue including an organ being in motion, the apparatus comprising:
- means for scanning the cross section by the ultrasonic beam to collect an ultrasonic echo signal reflected from the tissue in the cross section;
- means for obtaining two-dimensionally mapped velocities of movement of the tissue in the cross section every frame on the basis of the ultrasonic echo signal;
- and
- means for obtaining information of net movement of the organ with respect to a predetermined movement reference associated with the organ from the two-dimensionally mapped velocities of movement of the tissue in the cross section.

- means for scanning the cross section by the ultrasonic beam to collect an ultrasonic echo signal reflected from the tissue in the cross section;
- means for obtaining two-dimensionally mapped velocities of movement of the tissue in the cross section every frame on the basis of the ultrasonic echo signal;
- means for calculating a uniform velocity component corresponding to an entirely uniform movement of the tissue in the cross section on the basis of the two-dimensionally mapped velocities of movement;
- and
- means for removing the calculated uniform velocity component from each velocity of the two-dimensionally mapped velocities of movement in order to obtain information of net movement of the organ.
