Abstract :
In view of Magnetic Resonance Imaging(MRI) gradient coils is the directly determining factors of imaging quality and high-end application field requirements. Based on optimization theory about gradient coils performance index, Construction of the optimized scheme of Nuclear Magnetic Resonance gradient coils performance parameters and performance index testing platform, which is include back stepping design by Matlab and the simulation of electromagnetic field distribution with Ansoft, and the design of geometric structure and electric inductance, etc. performance parameters for permanent magnetism open architecture plate gradient coils ( x, y, z ), in order to satisfy with gradient field intensity, functionally gradient linearity, slew rate, gradient variation of inductance, etc. performance parameters for gradient coils. Experiment results show the scheme has some practical value in engineering.
