Abstract
Even when a region of interest (ROI) is changed on a frozen image, an elasticity image of ROI after the change can be displayed without executing re-measurement. An ultrasonic diagnostic apparatushas a control unithaving a first ROI setting unitand a second ROI setting unit. When ROI is set by the first ROI setting unitof the control unit, an elasticity information calculating unitsets an area larger than ROI as a calculation area, calculates distortion, elasticity modulus, etc. of a tissue corresponding to each measurement point on a tomographic image of the calculation area, generates elasticity information based on the distortion, the elasticity modulus, etc., and outputs the elasticity information to an elasticity information storing unit. The control unitchanges the position/size of ROI by the second ROI setting unitunder a state that the frozen image is displayed. The elasticity image constructing unitreads the elasticity information corresponding to the changed ROI from the elasticity information storing unit, forms an elasticity image of the changed ROI and displays it on an image display unit
