Problems solved by technology

In the existing vascular implantation, multiple vascular imaging examinations are performed during the implantation of the vascular stent to ensure that the stent will not touch the plaque during the advancement. This method will cause the patient to inject too much contrast agent and receive Excessive radiation, and because of the two-dimensional images obtained, it is not possible to accurately determine whether the stent will touch the plaque during the advancement of the vessel

Embodiment Construction

[0040] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0041] Such as figure 1 As shown, a stent release simulation method based on virtual imaging of a real vascular model, including:

[0042] S1. Constructing a three-dimensional image model of blood vessels.

[0043] Constructing a three-dimensional image model of a blood vessel includes the following steps: acquiring a CTA image of the blood vessel; constructing a three-dimensional image model of the blood vessel by using virtual imaging technology according to the CTA image of the blood vessel. CTA is also called non-invasive angiography in medicine (referred to as CT angiography, or CTA). Angiography is an interventional detection method. The contrast agent is injected into the blood vessel. This feature is used to diagnose vascular lesi...

Abstract

The invention discloses a vascular stent release simulating method based on virtual imaging of a real blood vessel model. The method comprises that a 3D blood vessel image model of is constructed; a position of a patch is determined according to the 3D blood vessel image model; a travel path of a vascular stent is planned according to position of the patch; and the vascular stent is sent to a target position according to the travel path, and is released. According to the method, release of the vascular stent is simulated in the 3D blood vessel image model the optimal travel path of the vascular stent is obtained, a doctor can be guided to release the vascular stent in practical operation, the dosage of injected contrast agent and received radiation of a patient is reduced, and the qualityof medical services is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a stent release simulation method based on virtual imaging of a real blood vessel model. Background technique [0002] Too much cholesterol in human blood can easily deposit on the inner wall of arteries to form plaques, which can cause atherosclerosis, eventually leading to excessive narrowing of the vessel lumen, insufficient or interrupted blood supply. At present, the treatment method of atherosclerosis widely adopts vascular stent implantation. [0003] Vascular stent refers to the placement of internal stents in the diseased segment on the basis of lumen balloon expansion to support the stenotic and occluded segment of the vessel, reduce elastic recoil and reshaping of the vessel, and maintain smooth blood flow in the lumen. Some internal stents can also prevent restenosis. Mainly divided into coronary stents, cerebrovascular stents, renal artery stents, aortic st...
