PURPOSE:To display extent of movement or speed of the movement part in a testee body in a ultrasonic diagnostic device. CONSTITUTION:The common set area of the speckle area is calculated by two pictures in time series obtained by ultrasonic wave transmitting/receiving means 1 and 2 transmitting and receiving the ultrasonic wave to a testee body 12, tomogram scanning means 3, 4, 5 repeatedly obtaining the tomographic picture data in the testee body containing the movement part with the reflection echo signal from the means 1 and 2 at the prescribed cycle, and tomogram scanning means 3-5. The device consists of an arithmetic modulation means 6 calculating the moving distance between pictures from the common collection area and luminance-modulating the image according to the moving distance, an accumulation means 8 inputting the arithmetic data from the means 6 and accumulating at least two pictures, picture display means 9 and 10 converting the arithmetic data from the means 8 into an analog signal at the display. Thus, the extent of the movement of the moving part between two pictures in time series can be displayed. |
