Embodiment Construction

[0073] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described The embodiments are only some of the embodiments of the present application, but not all of them. Based on the embodiments of this specification, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0074] The blood flow guiding device is used for the treatment of intracranial aneurysms. The principle is: when the stent is fully opened, the mesh of the stent is small enough to change the blood flow, and the blood flow forms a turbulent flow on the inner surface of the stent instead of entering the aneurysm. , resulting in thrombus formation withi...

Abstract

The embodiment of the invention discloses a simulation method, device and equipment, and belongs to the technical field of medical images and computers. The method comprises the steps of performing three-dimensional reconstruction based on to-be-processed craniocerebral image data to obtain a reconstructed blood vessel image; segmenting an aneurysm based on the reconstructed blood vessel image toobtain aneurysm parameters and parent artery parameters; optimizing the parent artery center line data to obtain optimized parent artery center line data, the optimized parent artery center line beinga homogenized center line; based on the aneurysm parameters, the parent artery parameters and the optimized parent artery center line data, obtaining a stent model of a stent for intervention and a release position of the stent for intervention; and simulating the stent for intervention to obtain at least one simulation effect of woven mesh display, adherence display, length display, metal coverage rate, expansion coefficient, angle change curve, diameter change curve and metal wire diameter.

Description

technical field [0001] This specification relates to the field of medical imaging and computer technology, in particular to a simulation method, device and equipment. Background technique [0002] Intracranial aneurysms, also known as cerebral hemangiomas, are mostly abnormal bulges that occur on the walls of intracranial arteries. They are the number one cause of subarachnoid hemorrhage, second only to cerebral thrombosis and high Blood pressure and cerebral hemorrhage ranked third. Intracranial aneurysms are divided into non-ruptured aneurysms and ruptured aneurysms. Most intracranial aneurysms are non-ruptured aneurysms. However, once a non-ruptured aneurysm ruptures, it will cause spontaneous subarachnoid hemorrhage and become A ruptured aneurysm has a fatality and disability rate of more than 50%, which seriously threatens the lives of patients. [0003] As an epoch-making product in the treatment of intracranial aneurysms, flow diverter (FD) is widely used in large, ...
