Abstract

The invention relates to an intracranial aneurysm virtual intervention stent implantation method and device, a computer device and a storage medium. The intracranial aneurysm virtual interventional stent implantation method comprises: acquiring data, wherein image data are acquired; And processing the data: segmenting the acquired image data and establishing the shape of the blood vessel to be evaluated; and obtaining a target blood vessel: obtaining a starting point and a terminal point in the blood vessel to be evaluated to obtain a target blood vessel; acquiring stent parameters: acquiringspecific parameter information of the virtual interventional stent; and processing the stent data: generating a three-dimensional point-line model of the stent in a free expansion state according to the acquired specific parameter information of the virtual interventional stent; and support bending deformation processing: carrying out bending deformation processing on the three-dimensional point-line model of the support in a free expansion state to obtain an expansion support image; and compression bracket processing: carrying out compression processing on the expansion bracket image to obtain a compression bracket image; and stent simulated release: placing the compressed stent image into a target blood vessel in a simulated manner.

Description

Technical field [0001] This application relates to the technical field of aneurysm treatment, in particular to a method, device, computer equipment, and storage medium for implanting an intracranial aneurysm virtual interventional stent. Background technique [0002] Cerebral hemangioma, also known as intracranial aneurysm, is a kind of tumor-like protrusion on the arterial wall caused by abnormal expansion of the lumen of the intracranial artery. The disease is a common intracranial vascular disease, which can be seen in 3% to 7% of the total population. Intracranial hemangioma can be divided into non-ruptured hemangioma (UIA) and ruptured hemangioma (RA). The vast majority of hemangioma is non-ruptured hemangioma (UIA), which will not rupture for life, and its annual rupture rate is only 0.05% . However, once the hemangioma ruptures, it will cause spontaneous subarachnoid hemorrhage, and the death and disability rate will exceed 50%. Among the deaths caused by cerebrovascula...
