| Abstract: | The structure design and optimum method of the two kinds of the solenoid coil on the basis of the preliminary field theory and active shimming are analyzed systematically.Some coil's structure pattern and high precise numerical calculation method of the coil's magnetic field are presented. The designed shim coils have been successfully used in 0. 04 T resistive magnet in the ultra low field MRI system. |
