Abstract

The embodiment of the invention discloses an aortic dissection evaluation method anddevice, equipment and a storage medium. The method comprises acquiring a to-be-processed image and clinical information of a current object, and constructing a geometric model comprising a target segmentation part according to the to-be-processed image; meshing the geometric model, determining an inlet and at leastone outlet of the geometric model, determining boundary conditions of the inlet and at least one outlet of the geometric model according to the to-be-processed image and the clinical information, andperforming hemodynamic simulation based on the boundary conditions; verifying the hemodynamic simulation result according to the clinical information; when the hemodynamic simulation result does notpass the verification, adjusting the boundary conditions of the geometric model, and performing hemodynamic simulation on the geometric model based on the adjusted boundary conditions; and taking theverified hemodynamic simulation result as an evaluation result of the aortic dissection. The aortic dissection is evaluated from the perspective of hemodynamics, and the accuracy of an aortic dissection evaluation result is improved.

Description

technical field [0001] Embodiments of the present invention relate to image processing technology, and in particular to a method, device, equipment and storage medium for evaluating aortic dissection. Background technique [0002] Aortic dissection (AD for short) usually means that the blood in the aortic lumen enters the aortic media-adventitia or the junction of media and adventitia through the intima tear on the aortic wall, tearing the aortic wall into two layers , a condition in which true lumen and false lumen are formed and extend along the longitudinal axis of the aorta, which can lead to aortic rupture in a short period of time and cause death of the patient, or the true lumen of the dissection is compressed by the false lumen to cause stenosis or even occlusion, and the blood is supplied by the true lumen Ischemic changes in vital organs can cause serious complications. [0003] In the prior art, blood vessel analysis software is generally used for blood vessel an...
