Title:
狭窄病変を有する血管数学モデルの合成方法及び装置
Document Type and Number:
Japanese Patent JP7414329
Kind Code:
B2
Abstract:
Disclosed are a method and a device for synthesizing a mathematical model of a blood vessel having a stenotic lesion. The method comprises: performing three-dimensional modeling according to a real-time diameter Dt of a blood vessel, a length L of a blood vessel centerline and a stenotic section to form a three-dimensional model of the blood vessel having a stenotic lesion section (S01); performing N-gon meshing along a circumferential surface of the three-dimensional model of the blood vessel to form a single-layer mesh model (S02); performing surface layering on the single-layer mesh model to form a double-layer mesh model, that is, a mathematical model of the blood vessel (S03). The present disclosure solves the problem of lacking a three-dimensional mesh model of a blood vessel for fluid dynamics analysis in the prior art and fills the gap in the industry. As a blood vessel wall has a certain thickness and a stenosis mainly occurs at an inner wall of the blood vessel, the mathematical model of the blood vessel is established as a double-layer mesh model having a certain thickness, and an inner-layer mesh model of which has elasticity and is able to correct the blood flow velocity, better approximating the actual state of the blood vessel.
