Abstract:
1. An apparatus for retrofitting an intraoral radiology positioning device comprised of an aiming ring, a bite block and a sensor basket attached to a guide arm, comprising: a near side cover; a far side cover; and a first collimation plate with a first collimation aperture; wherein the near side cover and the far side cover are adapted so as to releasably attach together about the aiming ring so as to hold the first collimation plate and position the first collimation plate so that the first collimation aperture restricts the size of an X-ray beam traveling through the aiming ring; wherein the near side cover is adapted to be positioned adjacent to a near side surface of the aiming ring while the far side cover is adapted to be positioned adjacent to a far side surface of the aiming ring so that the aiming ring is positioned between the near side cover and the far side cover and neither the near side cover nor the far side cover is mechanically secured by itself to the aiming ring.
