Fig. 1 Idealized sample floor plan illustrates site access
restriction considerations. Other MR potential safety issues, such as magnet
site planning related to fringe magnetic field considerations, are not meant
to be include herein. See Appendix 1 for personnel and zone definitions.
NoteIn any zone of the facility, there should be compliance with Health
Insurance Portability and Accountability Act (HIPAA) regulations in regard to
privacy of patient information. However, in Zone III, there should be a
privacy barrier so that unauthorized persons cannot view control panels.
