ULTRASONIC DIAGNOSTIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To clearly realize the effect of a contrast medium on an ultrasonic image while reducing the speckle noise in the ultrasonic image. SOLUTION: This ultrasonic diagnostic apparatus comprises an averaging arithmetic part 9 having a memory 91 for luminance-comparing the image data of the present frame with the image data of the previous frame by address correspondence and outputting data with averaging or without averaging according to the comparison result, and a Flip Flop circuit(FF) 92 for inputting a clock for updating the fame so that the image data of the previous frame is addressable to the image data of the present frame and retaining the image data of the previous frame.
