Abstract: A process for tracking an object within an inventory control space is provided. The space is illustratively a medical care delivery setting. An active radiofrequency (RFID) tag is encoded with a single-use code and associated with an inventory item. After a trigger event, the RFID tag transmits a modified broadcast. The single-use code that is a new number with at least one sparse digit or a new secondary number with a retained primary digit. An RFID tag configured to retain such a code scheme is provided. A hospital inventory item labeled with such an RFID tag is also provided.

Abstract: A system is provided for subject movement compensation during a medical procedure. The system uses passive radiofrequency identification tags associated with a subject, and at least one active RFID reader is positioned to interrogate the position of at least three such passive radiofrequency identification tags so as to triangulate the geometric position of a subject body tissue. The reader generates an output signal corresponding to a distance between said reader and a tag. A microprocessor calculates a displacement of a tag relative to the reader from said output signal to yield a value corresponding to subject movement. A medical device operates in synchronicity with the calculation corresponding to subject movement to compensate for subject movement during a treatment process in essentially real time. A process for subject movement compensation during a medical procedure is also provided.
