摘要:
Provided is an ultrasonic diagnostic apparatus provided with an elasticity evaluation technology that an error caused by a tissue structure has been reduced. The ultrasonic diagnostic apparatus that measures a velocity of a shear wave that propagates in a test object by utilizing an ultrasonic wave to evaluate elasticity of the aforementioned test object transmits and receives a first ultrasonic wave to the test object to detect a position and a size of the tissue structure of the test object and to automatically decide a measurement region except the tissue structure, transmits a second ultrasonic wave to the measurement region to make it generate the shear wave, and transmits and receives a third ultrasonic wave to the measurement region to measure an amount of displacement in association with propagation of the shear wave and to calculate the shear wave velocity by utilizing this displacement amount.
