Magnet designing method for magnet resonance imaging, involves determining field inhomogeneity followed by adjusting locations of main and buckling coil, and currents in correction coils

摘要

The method involves measuring field strength in the magnet bore at fixed number of points within a volume of large and small images. The field inhomogeneity is then found by comparing it with the peak-to-peak field measured between highest and lowest values of all measured points. Adjusting the location of main and buckling coils, and currents in correction coils is done.
