本論文為研究MRI掃描實際狀態主動脈與理想狀態主動脈之間的比較狀況，透過有限元素分析軟體COMSOL Multiphysics進行建模與數據分析。
MRI掃描主動脈是用成功大學醫院的MRI磁振造影系統提供磁相位資料，透過Matlab轉換流速數據資料，利用此資料計算血管壁座標，再輸入COMSOL來建模及流速模擬，最後分析結果；理想狀態主動脈則是使用COMSOL建立平滑血管壁的理想模型，輸入流速數據進行模擬。
經由COMSOL建模及模擬後，透過操作進行流速分佈、壓力分佈的數據圖與圖像分析，比較兩者的模擬差異，甚至經由同一個模型，輸入不同的流速資料，來分析不同流速時的狀況。

Due to the advancement of science and technology in recent years, medical attention has been paid to non-invasive examinations. Among them, the technology in the MRI is widely used because of its non-radioactive characteristics. The data provided by MRI includes a complete three-dimensional flow velocity field. After combining with COMSOL Multiphysics, it can be modeled and set, and then simple operations can be used to analyze the simulation results. This paper uses MRI flow rate data to write a program calculation in Matlab software to obtain the data required for modeling in COMSOL Multiphysics, and enter the flow rate setting value for simulation. Finally, the simulation results are analyzed, and image analysis of hemodynamics such as flow velocity profile, pressure profile, pressure gradient, wall shear stress, etc. can be performed.
