摘要

High-strength, high-slew-rate gradient coils have been designed to realize many important clinical imaging applicationsrnover human body in super conduct MRI systems. For instance, a high b-value in diffusion weighted imaging of humanrnbrain for identifying stroke requires a high gradient strength, and the high gradient slew rate is important for thernbrain-specific application of fMRI(functional MRI) in which high spatial resolution is the main goal. But for permanentrnmagnet MRI systems, their relative low fields have limited the use of these imaging applications. In resent years, asrnpermanent magnet MRI systems with higher and higher field are developed, these imaging applications are likely to carryrnout in these systems. Therefore, high performance gradient coils are also desired for these systems. An effective designrnmethod for gradient coils of permanent magnet MRI systems is presented in this paper.
