Abstract

The invention discloses a heart image four-dimensional context segmentation method, equipment, a storage medium and a device. The method comprises the following steps: constructing a point distribution model in a three-dimensional activity shape model according to a four-dimensional heart image; constructing an initial heart shape according to the four-dimensional heart image; processing the initial shape of the heart according to the point distribution model; obtaining an initial shape under the time phase of the diastolic period; and segmenting the image under the diastolic phase according to the three-dimensional activity shape model and the initial shape under the diastolic phase to obtain a segmentation result under the current time phase, the diastolic phase being the time phase corresponding to the maximum volume, and so that based on diastolic phase segmentation, the segmentation accuracy of the heart image is improved; and taking the segmentation result under the current timephase as the initial shape of the to-be-segmented heart image when the current time phase is adjacent to the current time phase, performing analogy in sequence to obtain segmented images of all time phases, and segmenting the images of each time phase of the heart one by one based on the segmentation result under the current time phase, thereby improving the segmentation efficiency of the heart image.

Description

technical field [0001] The present invention relates to the technical field of computer analysis of medical images, in particular to a method, equipment, storage medium and device for four-dimensional context segmentation of cardiac images. Background technique [0002] The heart is an important organ of the human body, and whether it works normally directly affects people's health. According to statistics, heart disease is one of the diseases with the highest mortality rate in the world. According to statistics, heart disease is one of the diseases with the highest mortality rate in the world, which has a huge impact on social and economic development. For this reason, it has very important social significance and use value to carry out new technology research on early diagnosis and treatment of heart disease. [0003] Due to the visibility and computability of medical images, research on early diagnosis of heart disease based on medical image segmentation has attracted mu...
