Blood Flow and Pressure Change Simulation in the Aorta with the Model Generated from CT Data

摘要

We have performed the blood flow and the pressure change simulation in the aorta with the model generated from CT (Computerized Tomography) data. There have been some previous researches related to the aortic valve and the blood flow in the aorta. Some works simulated the aortic valve behavior with artificial models, and others investigated the blood flow in the aorta with models generated from MRI (Magnetic Resonance Imaging) data. In this paper, we demonstrate the simulation of the blood flow and the pressure change in the aorta with a model generated from CT data, which model includes not only the aorta but also the left ventricle. In the simulation, blood flows into the left ventricle through the mitral valve, the pressure increases according to the blood flow that moves into the left ventricle through the mitral valve, and the aortic valve opens by the pressure increase in the left ventricle. Finally, we have confirmed that the pressure change in the left ventricle corresponds to a literature value.
