A radio frequency identification (RFID) system having the capacity to detect conditions of alignment, wherein the system may be used with hand-held, fixed-in-place, stationary, and permanently mounted apparatus. The system includes an RF interrogator configured for use with dental x-ray, medical imaging, film, and digital radiography apparatus, and may include a multiplicity of RF transponders or interrogators. An RF interrogator, an RF transponder, and an x-ray sensitive imaging device, and its holder are configured to be critically aligned to a dental x-ray machine head apparatus, rendering repeat imaging unnecessary. The x-ray emitter may be further configured to automatically obtain a desired x-ray image or configured so that the device cannot activate and provide a radiograph until alignment with the transponder and associated x-ray sensitive imaging device has occurred.

RFID transducer alignment system

A radio frequency identification (RFID) system having the capacity to detect various geometric parameters of alignment. The described system is configured for use with dental x-ray, medical imaging and treatment, and customary and digital radiography apparatus, but is not restricted to such apparatus or applications. The system may include a multiplicity of RF transponders, RF tags, and RF readers, wherein each RF tag may include one or more carrier receive/data transmit coils and wherein each RF reader may include one or more carrier transmit/data receive coils, and wherein each coil of an RF tag or RF reader may resonate at one or more, and/or, at the same or differing frequencies. An RF tag located about an x-ray sensitive film or device, and an RF reader located about a dental x-ray machine or apparatus, are configured to be critically aligned, one to the other, rendering repeat imaging unnecessary.
