基于整数规划的特殊永磁型磁体匀场技术的改进研究
Research Based on Integer Programming on Improvement of the Shimming Technology of Permanent Main Magnet for MRI Devices
本文针对磁共振成像(MRI)系统成像对磁体的要求,提出了一种基于整数规划的无源匀场数学模型。按照实际匀场时以测量平面的中心场值为参考基础,改进了原有的模型,进行了匀场模拟。匀场结果表明,该方法能快速有效地完成匀场过程。
he mathematical model of passive shimming based on integer programming for medical Magnetic Resonance Imaging (MRI) is researched in this paper. The model of integer programming is improved according to selecting the center magnetic field of measured plane as basic standard. The shimming is simulated at the same time. The results of computation indicate that the shimming process can be completed effectually by the reformative method.
