二维相位对比核磁共振成像的仿真研究
The Simulation Research of the 2 Dimensional Phase-Contrast Magnetic Resonance Imaging
摘要
Abstract
2D phase contrast magnetic resonance imaging (PC-MRI) is a very important technique for measuring the flow of the blood and cerebrospinal fluid. Choosing the correct parameter is very important for PC-MRI, because the PC-MRI is focused on imaging the flow, but the flow can very easily cause artifact on image which makes the measured result inaccurate. To do the simulation is very important to analyze the gradient spoiler for suppressing the flow artifact. This simulation includes the flow of the proton, the whole process of the signal acquisition and processing for MRI. The simulated phase-contrast image can be used to calculate the flow and compare with the programmed value. A flow phantom experiment has been carried out to validate the simulation result. The result indicates that our simulation and flow phantom experiment have good agreement.关键词
