Static and Electromagnetic Fields
The MR instrument consists of several components that produce various electromagnetic fields and a very high static magnetic field. Electromagnetic radiation may cause harm to the operator as well as affect the surrounding environment. The following topics will be addressed:
- Static magnetic field: The magnet provides a strong time-invariant magnetic field called static magnetic field.
- Gradient fields: Time-dependent magnetic fields.
- Radio frequency fields: RF coils driven by RF power amplifiers produce pulsed high frequency electromagnetic fields.
