Abstract
An active EMI shield for protecting medical instruments from mobile RF emitters uses RFID tags and tag readers to facilitate identification of an RF emitter entering the EMI shield. Clinicians and mobile RF emitters are tagged with RFIDs that indicate their identity, and possibly RF power level. Medical instruments are either tagged with RFIDs that indicate their identity and susceptibility to EMI, or equipped with RFID readers/EMI sensors. The proximity of the RF emitter relative to the medical instrument in terms of power density can then be determined by either position-sensitive RFID readers or the EMI sensors affixed to the medical instruments. The shield is executed by signaling to the tagged RF emitter when it reaches a predetermined proximity relative to the medical instrument.
