Coronary artery microcirculation condition evaluation device and method

Abstract

The invention provides a coronary artery microcirculation condition evaluation device and method. The coronary artery microcirculation condition evaluation device comprises an image acquisition moduleused for acquiring a CTA image of a heart part of a patient; an image segmentation module which is used for segmenting the CTA image to obtain a coronary artery image in a systolic period and a coronary artery image in a diastolic period; a volume acquisition module which is used for acquiring the volume of the systolic period and the volume of the diastolic period according to the coronary artery image of the systolic period and the coronary artery image of the diastolic period; a difference value acquisition module which is used for acquiring a volume difference value according to the volume of the systolic period and the volume of the diastolic period; and an evaluation module which is used for obtaining the coronary artery microcirculation condition of the patient according to the volume difference value. According to the coronary artery microcirculation condition evaluation device, the coronary artery microcirculation condition of the patient can be obtained by processing the CTAimage only by obtaining the CTA image of the heart part of the patient, and the coronary artery microcirculation condition evaluation device is easy to operate and easy to implement.

Description

technical field [0001] The invention belongs to the field of cardiovascular measurement, and relates to an evaluation device, in particular to a coronary microcirculation status evaluation device and method. Background technique [0002] Cardiovascular disease is one of the diseases with the highest probability of death in the current society. Using CT, MRI and other medical imaging equipment to scan and obtain medical images of the patient's heart, and use image processing technology to process and calculate medical images to obtain relevant indicators of the human body , is an important basis for clinical diagnosis of cardiovascular disease. [0003] The blood supply of the myocardium comes from the left and right coronary arteries at the root of the aorta, through coronary branches, coronary microvessels, and venules, and finally enters the right atrium through the coronary sinus or precardiac veins, and the coronary arteries in the epicardium often have vertical branches...

AI Technical Summary

Problems solved by technology

However, because coronary microvessels are very small, it is difficult to directly observe them through medical images, and it is even more difficult to obtain them through computer image segmentation technology. Therefore, it is difficult to evaluate the coronary microcirculation status of patients with existing technologies
