循環器疾患診断用の血管・血流解析技術の

In recent years, research has been conducted to extract 3D images of blood vessels using CT (computed tomography) and MRA (Magnetic Resonance Angiography) and apply them to diagnostic and medicinal support by analyzing blood flow using CFD (Computational Fluid Dynamic). However, CFD analysis takes a long time to calculate, and since the blood vessel wall is regarded as a rigid body, there is a problem that the stress inside the blood vessel wall cannot be calculated. In this report, we propose a method with a small computational load to analyze the coupled analysis of blood vessel wall and blood flow in the frequency domain.
