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 that of acquiring aneurysm parameters and parent artery parameters of to-be-processed craniocerebral image data, wherein the center line of the parent artery is a homogenized center line; based on the aneurysm parameters and the parent artery parameters, carrying out modeling according to the velocity, the time delta t and the growth distance position to obtain a stent simulation surface of a stent for intervention, wherein the position + = value * delta t, and when a preset constraint condition is met, the velocity is reduced to 0; and based on the stent simulation surface, simulating the stent for intervention to obtain at least one simulation effect of mesh grid 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, the blood flow diversion device is widely us...
