PURPOSE: An ultrasonic diagnostic device is provided to easily display an elastic image which accurately shows the elasticity of a biological tissue. CONSTITUTION: An ultrasonic diagnostic device includes an elastic image data producing unit, a physical quantity averaging unit, a comparing unit, a memory, and an image producing unit. The elastic image data producing unit sets a relation window in two echo data on the same sound ray. The physical quantity averaging unit produces the average of the physical quantity in a region to produce an elastic image of a biological tissue based on the elastic image data(EGD1, EGD3, EGD4). The comparing unit compares the average of the physical quantity at each frame by the physical quantity averaging unit with the preset average of the physical quantity. The memory memorizes the elastic image data. The image producing unit displays the elastic image of the frame as a moving picture. |
