Abstract
The apparatus includes a hand-held RF transducer having a transmit section for providing an energizing signal to cause a RFID tag associated with an object retained in the body of the patient to transmit an RF signal and a receiver section for receiving the RF signal transmitted by the RFID tag, as the patient's body is scanned. An auxiliary antenna array for receiving the transmitted RF signal transmitted by the RFID tag is situated in the mattress on the operating table under the patient. Signal processing electronics are connected to the receiver section of the transducer and to the auxiliary antenna array for determining and indicating when a RF signal from a tag has been received, representing that a tagged object remains in the body of the patient, and for decoding the RF signal to identify the object.
