Abstract

The invention discloses a right ventricle image segmentation method. The right ventricle image segmentation method comprises the following steps: S1, marking key points of an original heart image; S2, generating a key region rectangle according to the key points; S3, intercepting a heart area by using the key area rectangle; S4, performing pre-segmentation on the heart region to obtain a pre-segmentation result; S5, performing initial segmentation on the pre-segmentation result by using the key points to obtain an initial segmentation result; and S6, segmenting the right ventricle image in the initial segmentation result by using a level set algorithm to obtain a right ventricle image segmentation result. According to the right ventricle image segmentation method provided by the invention, the problem that the existing right ventricle segmentation result is unstable can be solved.

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, so the prevention and treatment of cardiovascular disease has gradually become a hot issue that people pay attention to. 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. Nowadays, with more and more imaging information, it is difficult for doctors to process massive amounts of data, so they have to use semi-automatic or automated segmentation methods to extract regions of inter...
