Abstract

The present invention discloses a right ventricular image segmentation method. The right ventricular image segmentation method includes: S1: marking key points of the original heart image; S2: generating a key area rectangle according to the key points; S3: using the key points The area rectangle intercepts the heart area; S4: Perform pre-segmentation on the heart area to obtain a pre-segmentation result; S5: Use the key points to perform initial segmentation on the pre-segmentation result to obtain an initial segmentation result; S6: Use the level set An algorithm is used to segment the right ventricle image in the initial segmentation result to obtain a right ventricle image segmentation result. The right ventricular image segmentation method provided by the present invention can solve the problem that the existing right ventricular segmentation result is unstable.

Description

technical field [0001] The invention relates to the technical field of image segmentation, in particular to a right ventricle image segmentation method. Background technique [0002] Nowadays, cardiovascular disease has gradually become the "number one killer" of human health, and the morbidity and mortality are still rising. Therefore, the prevention and treatment of cardiovascular disease has gradually become a hot issue of people's attention. Electron tomography (CT) and magnetic resonance imaging (MR) are widely used in Linchuan to diagnose heart disease because of their non-invasive and high imaging resolution, and have become an important auxiliary means for doctors to diagnose and treat. Image segmentation is a technology to extract people's regions of interest. With more and more imaging information nowadays, it is difficult for doctors to process massive data, so they have to use semi-automatic or automatic segmentation methods to extract regions of interest. The s...
