*(1) Power conditioning and/or uninterruptible power supplies shall be provided as indicated by the MRI manufacturer's power requirements and specific facility conditions.
(2) Radiofrequency (RF) shielding shall be provided for clinical MRI installations to attenuate stray radio frequencies that could interfere with the MRI imaging process.
*(3) At sites where magnetic field hazards or interferences are not adequately controlled through facility planning (i.e., by physical distance), the need for magnetic shielding shall be assessed by a certified physicist experienced in magnetic shielding design or equally qualified expert.
A2.2-3.4.5.8 (1) Power conditioning and voltage regulation equipment as well as direct current (DC) may be required.
A2.2-3.4.5.8 (3) Magnetic shielding can often be avoided in new construction when suite design and planning are employed to mitigate magnetic field hazards.
Magnetic shielding may be required to restrict the magnetic field plot. The area around, above, and below the MRI suite should be reviewed and evaluated for the following:
  • -Possible occupancy by person(s) who could have pacemakers or other implants
  • -Equipment that can be disrupted by a magnetic field. Examples include but are not limited to computers, CT scanners, and nuclear cameras.
After reviewing and evaluating the surrounding space, appropriate magnetic shielding may be required based on the type of MRI scanner to be installed.
