Abstract

본 발명은 혈류정보를 HSV 칼라시스템으로 맵핑하여 혈류/조직 신호를 분간하는 것을 특징으로 하는 칼라초음파진단기의혈류/조직 신호 분간 방법 및 그 장치에 관한 것으로서 본 발명에 의하면, 혈류정보를 HSV 칼라시스템으로 맵핑하고, 혈류신호와 조직신호를 분간하는 비교기에서 혈류신호의 V값과 조직정보신호인 그레이신호의 세기를 비교하여 출력함으로써효과적으로 분간할 수 있게하고, 디스플레이를 위하여 HSV'신호를 RGB로 변환시켜서 디스플레이한다.The present invention relates to a blood flow / tissue signal differentiation method and apparatus for color ultrasound diagnostic apparatus characterized by mapping blood flow information to HSV color system to distinguish blood flow / tissue signals. And the HSV 'signal is converted to RGB for display by comparing the V value of the blood flow signal with the intensity of the gray signal, which is a tissue information signal, and outputting the comparator that distinguishes the blood flow signal from the tissue signal. Display it.
