| Zusammenfassung: | The invention discloses an adaptive visual positioning method of heart blood flow vortex movement based on color doppler image information. The method comprises the following steps of according to the distribution conditions of blue areas and red areas of a color doppler ultrasound heart blood flow image, determining the approximate area of the blood flow vortex movement; in the rough positioning area, determining the accurate boundary of the blood flow vortex movement area; in the accurate positioning area, obtaining a speed vector distribution chart of blood flow vortex movement; according to the speed vector distribution chart of blood flow vortex movement, obtaining a plane streamline chart of blood flow vortex movement; according to the plane streamline chart of blood flow vortex movement, judging the volume, shape and position information of blood flow vortex movement. The method has the advantages that the defect of objective selection of interested areas of the existing method is overcome, the precisi |
