Problems solved by technology

However, the existing methods for visual positioning of blood vortex motion in the heart flow field based on Doppler images do not take into account the formation and development of blood vortex motion in the heart flow field. Low and poor repeatability, it is difficult to meet the needs of accurate quantitative evaluation of blood flow vortex motion

Abstract

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 precision of visual positioning of blood flow vortex movement of a heart flow filed is greatly improved, the solid foundation is laid for the accurate quantitative evaluation of blood flow vortex movement of the heart flow filed, and the accurate mechanical data support is also provided for the accurate evaluation of the heart mechanical function.

Description

technical field [0001] The invention relates to the fields of medical image processing and cardiac fluid mechanics research, in particular to an adaptive visualization positioning method for cardiac blood flow vortex motion based on color Doppler image information. Background technique [0002] The visual and quantitative evaluation technology of blood vortex motion in cardiac flow field is one of the key and difficult issues in the current research of cardiac fluid mechanics. Among them, the precise positioning of the blood vortex motion is the basis for the effective implementation of the visual quantitative evaluation of the blood vortex motion. At present, there are three main types of visual positioning methods for blood flow vortex motion in the cardiac flow field: [0003] 1. Visual positioning of blood vortex movement based on MRI images; [0004] 2. Visual positioning of blood vortex movement based on ultrasound microbubble contrast images; [0005] 3. Visual pos...
