Abstract: An interface in a color Doppler ultrasound spectrum mode is generated on a display screen. In the interface, at a sampling preparation stage, a plurality of sampling instruction receiving regions are generated on a first position where a part of pixels of sampling tools are located and other positions. Instructions given in the regions are configured to control the sampling tools to change sampling ranges and sampling directions and pulse repetition frequencies. At a blood flow spectrum display stage, the sampling instruction receiving regions are closed; and a blood flow spectrum image control instruction region is generated to change a position of a blood flow spectrum baseline, and change an ultrasound signal gain and a spectrum speed. A computer program is stored to implement the operation method for the above color Doppler ultrasound spectrum mode interface.

Abstract: A generation method and device for a blood flow spectrum envelope includes: importing an image, then finding a connected domain; obtaining a contour map through the connected domain; marking coordinates of contour pixel points on the contour map; and connecting all the coordinates to form a blood flow spectrum envelope. A program stored in the storage medium or a processor of an ultrasound device has the steps of the generation method for the blood flow spectrum envelope. The blood flow spectrum envelope is automatically found; and when the image is continuously collected by ultrasound, the envelope is generated in real time according to the image collected by ultrasound in the disclosure to analyze a blood flow.
