Ultrasonic diagnostic apparatus
First Claim
1. An ultrasonic diagnostic apparatus including an ultrasonic probe having ultrasonic transducers for emitting ultrasonic waves toward a body part in a living body and receiving echo waves from said body part, said ultrasonic diagnostic apparatus generating an ultrasonic image from sound ray data which is digitized equivalent to said echo waves and displaying said ultrasonic image, said ultrasonic diagnostic apparatus comprising:
- a vibration signal acquisition section for acquiring vibration signal based on cyclic vibrations emanating from said living body; and
an elasticity image generating section for obtaining said sound ray data of plural frames corresponding to plural points in one cycle of said vibration signal when receiving timing signals synchronized with said plural points and for generating an elasticity image based on said plural frames of said sound ray data, said elasticity image indicating stiffness of said body part.

Abstract
An ultrasonic diagnostic apparatus includes an ECG memory storing ECG signals based on motion of a heart of a living body, an ECG A/D converter, and an elasticity image generating section. Upon receiving timing signals from a CPU synchronized with two points a and b in one cycle of the ECG signal, the elasticity image generating section obtains from a cinememory two frames of sound ray data of a body part to be examined. The two frames of the sound ray data correspond to the two points a and b respectively. A strain St is calculated from the obtained sound ray data. An elasticity image quantitatively indicating stiffness of the body part is generated on the basis of the calculated strain St.
