Abstract

The invention discloses a coronary artery calcification lesion full-automatic segmentation method based on chest flat scanning CT, and the method comprises the following steps: carrying out the preprocessing of an original chest flat scanning CT image, and obtaining preprocessing data; inputting the preprocessed data into a heart segmentation model, and segmenting a heart region in the original chest flat-scanning CT image to obtain a heart segmentation image which corresponds to the original chest flat-scanning CT image and contains the heart region; screening suspected coronary artery calcification lesions in the heart area; extracting a plurality of candidate sample blocks from the screened suspected coronary artery calcification lesions; and based on the plurality of candidate sample blocks and the corresponding coordinates of the candidate sample blocks in the coordinate system corresponding to the original chest horizontal scanning CT image, obtaining coronary artery calcification focus segmentation results of the candidate sample blocks by using a calcification focus segmentation model. According to the method, a coarse-to-fine strategy is adopted, a two-stage deep neural network is used for achieving full-automatic coronary artery calcification focus segmentation based on chest flat scanning CT, and a good segmentation result can also be obtained for data with large noise.

Description

technical field [0001] The present invention relates to the technical field of medical image segmentation, in particular to a method for fully automatic segmentation of coronary artery calcification based on chest plain CT scan. Background technique [0002] At present, the morbidity and mortality of cardiovascular disease are still on the rise, and its mortality rate still ranks first. However, the elderly with cardiovascular disease have weakened immune function and are more likely to be infected with other diseases and turn into critically ill patients. Therefore, it is particularly necessary to realize the early diagnosis of coronary heart disease. Sufficient evidence-based medical evidence supports that coronary artery calcification is an independent risk factor for adverse cardiac events in asymptomatic patients. [0003] Quantitative analysis of coronary artery calcification (CAC, Coronary Artery Calcium) can evaluate the possibility of cardiovascular disease. Cardi...
