Abstract
A computer executes: calculating a first volume distribution (v.d.) of magnetic materials on a shim tray, based on a first magnetic field strength distribution (m.f.s.d.) in a magnetic field space (S); acquiring a first composite distribution (c.d.) representing a volume by addition of volumes of magnetic materials for each region of the shim tray, and positions of the regions (S); calculating a virtual m.f.s.d. created by magnetic materials supposed to be arranged as in the first c.d. (S); calculating a second m.f.s.d. by addition of the first m.f.s.d. and the virtual m.f.s.d. (S); calculating a second v.d. of magnetic materials on the shim tray, based on the second m.f.s.d. (S); acquiring a second c.d. representing a volume by addition of volumes of magnetic materials for each region, and positions of the regions (S); and displaying the positions of regions and the volumes in the first c.d. and second c.d. (S).
