PURPOSE: To enable accurate image diagnosis by finding how each image data of plural numbers of frame memories within a color digital scan converter is delayed from the trigger signal of a living body wave detector, and thereby reading out the image data from each corresponding frame memory in order of small delay.
CONSTITUTION: It is possible corresponding to each frame memory by a delay memory section 23 connected with a central processing device 15 to memorize how each image data of plural numbers of frame memories within a color DSC 7 is delayed from the trigger signal of a living body wave dector 16 so that the image data can be read out from each corresponding frame memory in order of small delay based on the read out signal from the delay memory section 23 so as to be indicated on an indicating section 10. Hence, the state of blood stream with time can be precisely indicated while being matched with the movement of a heart, and concurrently the image data of a high frame rate can be obtained in a short time. By this constitution, time required for examination can be shortened, mental burden against the living body to be examined can thereby be reduced.
