Abstract
An ultrasonic diagnostic apparatus capable of accurately providing an elasticity modulus by actually measuring the pressure in an ultrasonic scanning region.
The ultrasonic diagnostic apparatus comprises a pressure bag installed on the ultrasonic transmitting/receiving surface of the ultrasonic probe and filled with a liquid, a liquid charging/discharging means for inflating or deflating the pressure bag by charging/discharging the liquid into/from the pressure bag, a pressure measuring means for measuring the pressure of the liquid placed in the pressure bag, and a pressure calculation means for calculating the pressure in the ultrasonic scanning region of an object to be examined in contact with the pressure bag according to the information on the pressure measured by the pressure measurement means.
An elasticity information calculation means calculates the elasticity modulus using the information on the pressure.
