Problems solved by technology

However, it is not yet possible to explain how these factors contribute to the increased risk of aneurysm rupture
[0004] With the development of cerebral aneurysm medical imaging technology and computational fluid dynamics, it has been recognized that the possible mechanism is that the change of cerebral aneurysm geometry leads to the change of intratumoral hemodynamic indicators, which leads to Growth and rupture of brain aneurysms

Abstract

The invention discloses a cerebral aneurysm hemodynamic index evaluation method, system and device and a medium. The evaluation method comprises the following steps: acquiring human body cerebral artery image data; carrying out anatomical modeling on the human body cerebral artery medical image data to obtain a cerebral aneurysm anatomical model; fluid mechanics calculation processing is conductedon the cerebral aneurysm anatomical model, and outputting a calculation result; and adding the calculation result to a corresponding position of the cerebral aneurysm anatomical model, and carrying out visual display of hemodynamic indexes. According to the method, the system, the equipment and the medium, the hemodynamic indexes of the cerebral aneurysm can be obtained according to the medical image data of the human cerebral artery. Therefore, the relationship between the hemodynamic characteristics and the occurrence, development and rupture of the aneurysm can be analyzed based on the obtained hemodynamic indexes, and a theoretical basis is provided for risk factor assessment and interventional therapy of the cerebral aneurysm.

Description

technical field [0001] The present invention generally relates to the technical field of computer image processing, and in particular relates to a method, system, device and medium for evaluating cerebral aneurysm hemodynamic indexes. Background technique [0002] Cerebral aneurysm or intracranial aneurysm is a sac-shaped or spherical bulge protruding from the cerebral artery wall formed by abnormal expansion of the cerebral artery lumen. The pathological changes mainly include fusiform expansion or limitation of the cerebral artery trunk or its branches. Cystic changes. There is an increasing incidence of cerebral aneurysms, the rupture of which can lead to intracranial hemorrhage, which, depending on the severity of the bleeding, can lead to brain damage or death. Clinically, the timely and effective treatment of cerebral aneurysms mainly depends on the timely and accurate diagnosis of the nature, type and adjacent anatomical relationship of the lesion. [0003] Due to t...
