ULTRASONIC DIAGNOSTIC SYSTEM

摘要

PURPOSE:To display a velocity vector of a moving part, for example, facilitate dynamic observation of a blood vessel by performing an accumulation processing of a plurality of differential images in an ultrasonic diagostic system. CONSTITUTION:An accumulator 8 is provided to perform an accumulation so that at least two images or more are added in a differential image data generated and outputted from a subtracter 6 while the differential image data does not vanish from the images added and the image data subjected to the accumulation processing with the accumulator 8 undergoes a color processing with a color encoder 9. Moreover, a differential image colored and a black and white tomographic image are overlapped with an adder 10 to be supplied to a D/A converter 11 and a display device 12 as image display means. Thus, the accumulation processing of a plurality of differential images is accomplished to display a velocity vector of a moving part.
