Abstract

Based on target field method, the article designs gradient coils for a permanent MRI magnet model. By simulating, winding and testing, the result verifies the validity and feasibility of target field method used in gradient coils design of permanent magnet MRI; moreover, shielded coils can restrain eddy current and can be designed based on target field method easily. The simulated results show that the effect of restraining eddy current is notable. So, the permanent magnetic MRI gradient coil can be designed by target field method. Gradient coils generate the linearly gradient field; and shielded coils restrain the eddy current.
