Components of an MRI scanner and related safety issues

Components of an MRI scanner and related safety issues
Component Function Safety concerns
Main magnet Creates a large magnetic field across the field of view to enable magnetic resonance signal from tissue sufficient for imaging
  • Translation and torque of ferromagnetic objects
  • Interference with electronic device function
Gradient coils Creates rapidly changing magnetic field gradients to encode spatial information on the image
  • Current induction and heating in metal implants
  • Interference with electronic device function
  • Noise and acoustic injury
Radiofrequency coils Serves as signal receivers and sometimes also transmitters, by creating an electromagnetic field at the resonant frequency of the nuclei
  • Current induction and heating in metal implants
  • Interference with electronic device function
MRI: magnetic resonance imaging.
