<p>An ultrasonic probe (11) has a plurality of ultrasonic transducers (UTs) (27). Each UT transmits ultrasonic waves and receives echo waves. In a B/A coefficient acquisition mode, every time a transmission of the ultrasonic waves and reception of echo waves takes place, ultrasonic waves for heating are transmitted to heat an object of interest. An HI processor (55) calculates a non-linear B/A coefficient based on a harmonic component of a detection signal from the UT. The HI processor acquires information of changes in the B/A coefficient while the obj ect of interest is heated with the ultrasonic waves for heating. A DSC (53) displays the information of the B/A coefficient together with an ultrasonic image (60) on a monitor (15).</p> |
