ULTRASONIC COLOR DOPPLER IMAGE SYSTEM, AND CLUTTER SIGNAL FILTERING METHOD FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an ultrasonic color Doppler image system.;SOLUTION: The ultrasonic color Doppler image system includes an operation part for computing an average value related to an IQ signal in each pixel of an ultrasonic color Doppler image including a plurality of pixels, and generating a multiplication operation value using the computed average value; a comparing part for comparing the generated multiplication operation value with the average value; and a masking part for masking the pixels based on the compared result. The operation part selects a reference average value in consideration of the scale of the computed average value in the plurality of pixels, and generates the multiplication operation value by multiplying the selected reference average value by a preset scale factor.;COPYRIGHT: (C)2011,JPO&INPIT
