Abstract:
A device (10) configured to detect the presence of metal artifacts in a patient's eye includes a head mount (14) configured to receive at least a portion of the patient's head. At least one inductor coil (12) is disposed on or in the head mount and positioned to inductively couple with at least one eye of the patient's head received into the head mount. An inductance meter (18) is operably connected to the at least one inductor coil to measure an inductance as a change of frequency of the at least one inductor coil. A processor (22) is programmed to: determine whether the inductance is greater than an inductance threshold value; and generate an indication of at least one metal artifact when the inductance is greater than the inductance threshold value. A display component (24) is configured to display the indication.
