PROBLEM TO BE SOLVED: To easily compare an image obtained at present with a reference image in the past by an ultrasonic diagnostic device. SOLUTION: Display attributes such as hues and the like of a tomographic image in the past stored in a storing part 32 are converted by an image data processing part 36. For example, the colored reference image is superimposed with a monochrome image of interest presently obtained from a probe 16 at DSC 24 to be displayed on a display part 40 as an overlay image integrated into one image. Moreover, a correlation index calculation part 30 calculates a correlation coefficient of data between the image of interest and the reference image. If a comparator part 34 detects that the correlation coefficient has exceeded a threshold, the image of interest in the overlay image is kept at a standstill at an image similar to the reference image, and the image of interest at this time is stored in a storage part 32. |
