Abstract

PURPOSE:To obtain a high grade color flow mapping image, by calculating brightness from the data of the small region of complex data and obtaining hue and saturation on the basis of the data of a slightly wide region to resolving the same into a color display signal along with a B-mode video signal to display the MTI image of white and black display by a color. CONSTITUTION:The output signal of a receiving beam former 1 is inputted to MTI filters 5a, 5b to fetch only a signal having Doppler shift and said signal is written in an MTI video file 6 in a form of complex data. Complex data of 16 P-regions are taken out and the average value V becoming the brightness evaluation value of an MTI image is calculated by an operation circuit 7. Data of S-regions of a slightly wide range are read and the direction and width of Doppler shift are operated by DSP 8 and the evaluation values of the hue and saturation of the S-region are obtained to be outputted as a B-mode video signal by an amplifying and detecting circuit 10. The output signal is written in one memory at every one transmission and reception by a B-mode video file 12 and the data of the pixel at the position corresponding to the region P is fetched at the point of time when transmission and reception of 16 times are finished and the average value W becoming the brightness value of a B-mode white and black image is calculated in an operation circuit 13.
