用于小口径5 T磁共振成像系统的梯度线圈和1H/13C双共振射频线圈研制
Development of Gradient Coils and 1H/13C Dual-resonance RF Coils for a Small-bore 5 T MRI System
摘要
Abstract
Based on the independently developed 5 T magnetic resonance imaging(MRI)system and research needs of 13C metabolic MRI,a gradient coil and 1H/13C dual resonance radiofrequency(RF)coil system for small-bore MRI were designed.The gradient coil was designed by using the finite-difference stream function method,and the RF coil was designed as a saddle coil combined with a surface coil in a dual-resonance scheme.Numerical simulation analysis of the magnetic field distribution was carried out by using the finite-element method,and a set of gradient and RF coils for small-bore 5 T 13C MRI was successfully developed.The feasibility of the design scheme was verified using a home-made 5 T MRI system,and the magnetic resonance images of 13C-labeled urea phantom and 1H magnetic resonance images of mice head were acquired by experimental tests,which lays a foundation for 13C metabolic MRI based on dynamic nuclear polarization in the future.关键词
