摘要
Even if there is a restriction in an amount of magnetic pieces which can be disposed at each position in a shim tray, a distribution of a static magnetic field is measured so that an error magnetic field between the distribution of the static magnetic field and a target magnetic field is calculated, and respective reachable magnetic field homogeneities in a case where the magnetic pieces are disposed at one or more of the plurality of positions in the shim tray are calculated while changing the target magnetic field. The target magnetic field is selected in which an amount of magnetic pieces at each of the positions in the shim tray is equal to or less than a predetermined upper limit value, and the reachable magnetic field homogeneity is equal to or less than a predetermined value.
