Development of Open Simulated Permanent Magnet for MRI Using NdFeB

摘要

MRI system is an advanced medicine clinical examination equipment. This ppaer will given an introducting of the structure of the 1:4 open simulated magnet which has been designed and calculated, and of the measurement result of the magnetic field, according to the requirement of the MRI system. This work is useful for the future development of the open magnet for MRI system.
