Problems solved by technology

[0003] In the existing technology, manual selection and classification of calcified areas are steps that cannot be omitted. Only after manual labeling and classification of calcified areas can the automatic analysis software system be used to calculate the calcification integral of the calcified area. The calcified area is a body in three dimensions. The traditional method of artificially marking the calcified area is to mark the calcified area on each layer of slices, which may cause several slices belonging to the entire calcified area to be Misclassification increases the error in the selection and classification of coronary calcification areas. At the same time, the process of labeling and classification of calcification areas is cumbersome and inefficient

Abstract

The invention provides a method, device and system for obtaining coronary-artery-calcification area classification, and relates to the technical field of calcification area selection. The method includes the steps that coronary-artery areas are obtained based on obtained three-dimensional information of CT plain scan information; suspected calcification areas are obtained from the obtained coronary-artery areas according to the certain condition; according to the preset condition, whether the suspected calcification areas need to be cut or not is judged, suspected calcification areas meeting the condition are cut; according to the characteristics of the cut suspected calcification areas, the suspected calcification areas are classified, and the classified suspected calcification areas areobtained. According to the method, device and system for obtaining coronary-artery-calcification area classification, the technical problems that calcification areas are misclassified when the calcification areas are manually marked, and coronary-artery-calcification-area selection and classification are large in error, complex in process and low in efficiency are solved, and coronary-artery-calcification-area selection and classification are simple in structure, high in efficiency and small in error.

Description

technical field [0001] The present invention relates to the technical field of calcification region selection, in particular to a method, device and system for obtaining classification of coronary artery calcification regions. Background technique [0002] Coronary Artery Calcium (CAC) score is an imaging examination method widely used in the assessment of cardiovascular risk in moderate risk population. In the prior art, when calculating the coronary artery calcification score based on unenhanced computer tomography (Computed Tomography, CT) information, it is necessary to manually select the coronary artery calcification area and classify the selected coronary artery calcification area, and then use the processing software to The classified calcified areas are calculated as integrals. [0003] In the existing technology, manual selection and classification of calcified areas are steps that cannot be omitted. Only after manual labeling and classification of calcified areas...
