BACKGROUND OF THE PRESENT INVENTIONThis invention relates to an ultrasonic diagnostic equipment which is possible to measure noninvasively the movement velocity signal of a part of heart, artery and the other organs by using ultrasonic wave, especially relates to an ultrasonic diagnostic equipment usable to measure small vibrations in myocardial tissues superimposed on a large amplitude vibration of heartbeat.
EXPLANATION OF PRIOR ARTThe techniques for ultrasonic diagnostic equipment are progressed highly in Japan, and there is not in the world a precedent study on "measurement of a small amplitude vibration of myocardial tissues superimposed on a large amplitude vibration of heartbeat" and the diagnostic equipment using the vibration measuring methods.
On the other hand, the electrocardiogram and the phonocardiogram analysis have their history over a hundred year, and their various meas...
