摘要：
According to one embodiment, an ultrasonic diagnostic apparatus includes an ultrasonic probe, transmission unit transmitting a first ultrasonic wave for generating a shear wave in an object to a first region and a second ultrasonic wave to a second region, reception unit generating a reception signal based on the second ultrasonic wave, displacement amount calculation unit calculating a displacement amount of a tissue accompanying propagation of the shear wave to the second region by using the reception signal, arrival time decision unit deciding an arrival time when the shear wave has arrived at each position in the second region, based on a temporal change in the displacement amount concerning the each position, and image generation unit generating based on the arrival time and predetermined pixel values corresponding to the arrival times, a shear wave arrival time image with the pixel values being assigned corresponding to the arrival times.
