摘要

本文通过对鸟笼线圈原理和阵列线圈去耦原理的分析,提出了一种适用于自主研发的多核并行磁共振成像(MRI)系统的双核并行成像线圈设计方案,并在电感去耦的基础上提出LC并联trap去耦法,提高了去耦方法的可适性.依据设计方案制作了1H/31P双核并行成像线圈,并将其应用于4.7 T磁体系统,利用自主研发的多核并行MRI系统进行了并行成像实验测试,成功获得了1H和31P的并行磁共振图像,验证了设计方案的可行性.

Abstract

Based on the principle of birdcage coil and the decoupling theory of array coil, a design scheme for dual-nuclear magnetic resonance imaging (MRI) coil is proposed. A LC parallel trap is used to improve the adaptability of the inductive decoupling scheme. According to the design scheme and simulation, a 1H/31P dual-nuclear parallel MRI coil is fabricated for a 4.7 T system. Dual-nuclear parallel imaging experiments are carried out on a custom-built MRI system to verify the feasibility of the coil design.
