Abstract
Abstract A wheelable chair for retaining a patient in an immobile position for radiographic purposes is provided with an articulated arm and an X-ray cassette holder. The holder is positioned by means of the articulated arm in a manner such that it engages with the chest of the patient in a manner sufficient to support and retain the patient in the proper position. Further retention is provided by means of straps or belts interconnecting the cassette holder with the patient, a set of straps for retaining the hands of the patient in a proper position on the holder, and a chin rest which will properly position the head of the patient during the radiographic exposure. The chair, itself, is manipulatable by means of wheels so as to properly position the patient relative to the X-ray device.
