To improve the frame rate of an ultrasonic diagnostic apparatus for displaying an elasticity image by detecting shear waves generated by push pulses (PPl, PP2). After first and second push pulses (PPl, PP2) have been simultaneously transmitted to different positions, each of a first ultrasonic detecting pulse (DPI) and a second ultrasonic detecting pulse (DP2) for detecting each respective shear wave generated by each of the first and second push pulses (PPl, PP2) is transmitted in a different acoustic line, and in a period after the first ultrasonic detecting pulse (DPI) has been transmitted and before the first ultrasonic detecting pulse (DPI) is transmitted again in the same acoustic line, the second ultrasonic detecting pulse (DP2) is transmitted. |
