Free breathing coronary artery scanning image lesion analysis system for old people

Abstract

The invention discloses an old people free breathing coronary artery scanning image lesion analysis system, relates to the technical field of scanning image lesion analysis, and aims to solve the problem that the accurate condition of a patient cannot be obtained according to a scanning image. A diameter method and an area method are combined with the contrast agent filling condition to judge the stenosis degree and hemodynamic change, lesions are analyzed from the double angles of morphology and function, comprehensive information is provided for clinical decision making, and the heart stenosis degree and the hemodynamic change are judged by recognizing R wave peak values, dividing heart time phases and combining time matching of respiratory signals and projection data. The characteristics of the heart in different motion states and breathing stages can be accurately captured, artifact interference caused by cardiac pulsation and breathing motion is effectively avoided, a reconstructed image is clearer and more accurate, all links are closely associated and the target is clear from scanning type confirmation to CT and injector parameter sequential setting, the working efficiency is improved, and the accuracy of the reconstructed image is improved. And quality control and process management are facilitated.
