Abstract:
1. Apparatus for dental and facial imaging, the apparatus comprising: a controller; a rotatable gantry; a source of penetrating radiation mounted on the gantry and including a beam limiter with a plurality of doors; and a detector of penetrating radiation mounted opposite the source on the gantry so that when a head of a patient is positioned between the source and the detector the axis of rotation of the gantry passes through the patient's head; wherein the detector is mounted translatably on the gantry between a first position and a second position and includes a first stop positioned at the first position and a second stop positioned at the second position, wherein movement of the detector between the first position and the second position is controlled so that the movement of the detector is slowed in a first direction before the detector reaches the first stop and movement of the detector is slowed in a second direction before the detector reaches the second stop, wherein the controller is configured to coordinate movement of the rotatable gantry, the plurality of doors of the beam limiter, and movement of the detector.
