Patent ID: 8294461

Claim:
An apparatus configured for detecting electromagnetically coupled RF current producing objects in a body undergoing a magnetic resonance (MR) imaging prescan, as a prudent safety measure before performing a full MRI imaging scan comprising: a magnetic resonance imaging excitation and detection system; and a controller electrically connected to the magnetic resonance imaging excitation and detection system, comprising: a display; at least one processor; and non-transitory computer readable media code, that when implemented by the at least one processor causes controller and the magnetic resonance imaging excitation and detection system to perform a series of method steps comprising: A) scanning the body with reverse circularly polarized non-tissue damaging RF; B) detecting MR signals generated by the electromagnetic coupling of the reverse circularly polarized non-tissue damaging RF with the electromagnetically coupled RF current producing objects in the body C) using the detected MR signals in order to determine a risk value to the body, derived from the electromagnetically coupled RF current that indicates the presence of dangerous magnetic field coupling; and D providing the risk value to a user in order to determine the prudence of performing a full MRI imaging scan, on the body.
