Developments in MR systems are allowing for siting which does not follow the typical “4 zone” architecture, removing barriers for MR implementation. A consequence of this is that these systems are nearer to elements of a building or hospital that may cause field distortions and cannot be resolved by shimming. This work quantifies the field distortions due to two typical elevators along a hallway and compares the distortion to a fit using a magnetic dipole approximation, verifying a 1/r³ field behaviour. This demonstrates the need for MR system placement guidelines which mitigate potential field stability concerns due to building elements.
