Abstract

The present invention provides a method and a system for medical image automatic segmentation. The method for medical image automatic segmentation comprises: obtaining a salient image of a to-be-trained medical image by using a visual attention model, and using the salient image to train parameters of a deep learning neural network; obtaining a salient image of a to-be-segmented medical image by the visual attention model, and inputting the to-be-segmented medical image to the trained deep learning neural network for segmentation, to obtain an initial segmentation result; using the initial segmentation result to construct an initial contour of a statistical shape model and to optimize the statistical shape model, and using the optimized statistical shape model to segment the to-be-segmented medical image. The method combines the statistical shape model and the deep learning model, and calculated amount of matching operation in the statistical shape model is reduced by using the initialsegmentation result of the deep learning network, thereby realizing fast and accurate segmentation of the three-dimensional medical image by the statistical shape model.

Description

technical field [0001] The invention belongs to the application field of computer analysis technology of medical images, and in particular relates to an automatic segmentation method and system of medical images. Background technique [0002] In recent years, with the continuous development of medical diagnosis and imaging technology, various computer-aided analysis methods of medical images have been widely used in predicting diseases and guiding interventional treatment. The heart is the most important organ of the human body, which is responsible for running blood to all parts of the body. Heart disease directly affects people's life and death. 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. ...
