Abstract

The invention provides a method, apparatus and system for calculating coronary artery calcification integral, and relates to the technical field of calcification score. The method comprises: the coronary artery regions are obtained based on plain CT information, Suspected calcification regions are obtained from the acquired coronary artery regions according to certain judgment conditions, and thesuspected calcification regions are classified according to the image characteristics of the suspected calcification regions to obtain the classified coronary artery calcification regions, and the coronary artery calcification scores are obtained based on the calculated calcification scores of the classified coronary artery calcification regions. The invention provides a method, apparatus and system for calculating coronary artery calcification integral, , which can alleviates the technical problems of inaccurate marking or inaccurate marking range and low efficiency of artificially marking the coronary artery calcification area in the prior art, thereby inaccurate integrating of the coronary artery calcification area, low efficiency of calculating integrating and large error, thereby improving the efficiency of calculating the coronary artery calcification integral and reducing the error of calculating.

Description

Technical field[0001]The present invention relates to the technical field of calcification points, in particular to a method, device and system for calculating coronary artery calcification points.Background technique[0002]Coronary Artery Calcium (CAC) score is an imaging method widely used in the assessment of cardiovascular risk in people at moderate risk. In the prior art, when calculating the coronary artery calcification score based on unscanned electronic tomography (CT) information, the physician needs to manually mark the calcification area, and then use the automatic analysis software system to calculate the score for the marked calcification area , Or need to obtain Computed Tomography Angiography (CTA) information and CT information, obtain the patient's blood vessel information through CTA information, and overlap the blood vessel information obtained by CTA and plain scan CT information to obtain the corresponding suspected calcification area to determine calcification ...
