[0039] Describe below in conjunction with accompanying drawing:
[0040] A level set segmentation method of left and right ventricles based on cardiac anatomy:
[0041] S1. Preliminarily segment the cardiac MRI (Cardiovascular Magnetic Resonance, CMR) to obtain a binary image including the heart and other tissues around the heart. Manually determine the position of the center point of the left and right ventricles in an interactive manner, and extract the Initialize the outline of the binary image of the left and right ventricles; firstly, perform step S1 to perform preliminary segmentation on the two-dimensional magnetic resonance image, and obtain a binary image including the heart and other tissues around the heart. By interactively determining the positions of the center points of the left and right ventricles, the binary image initialization contours of the left and right ventricles can be extracted according to the positions of the center points.
[0042] Among them, th...
