The most common form of RF interference comes from noise generated from nearby electrical equipment (transformers, motors, pumps) or electronic devices (computers, pulse oximeters, cardiac monitors). It is performed by placing heavy copper plates along the walls of the scanner room. Superconducting scanners are the most expensive to site due to their size, fringe fields, and cooling requirements.
