要約(英語): MRI (Magnetic resonance imaging) generates a strong magnetic field. This strong magnetic field may cause adverse effects on other medical equipment and cardiac pacemakers in the hospital. To prevent them, ICNIRP regulates the leakage magnetic field outside the room to within 0.5mT, and the top, bottom and side surfaces of the MRI room must be enclosed with ferromagnetic walls. However, its shape gives the subject a feeling blocked-up. Recently, it has been recommended to develop an open-type magnetic shield room that has an opening on the side and can take in light and scenery into the MSR. However, the open magnetic shield room has a problem that the volume of the ferromagnetic material increases due to the shield shape of the opening.In this study, in order to propose the open type MSR with a ferromagnetic volume equal to or less than that of the closed type model, we analyzed shield position, number of divisions in the X - Z plane and the width of both ends.
