ABSTRACT:
An x-ray film cassette holder especially adapted for use in radiography of the temporomandibular joint is disclosed. Slideable horizontal adjustment of the cassette holder is provided by a horizontal tray disposed at a vertically and rotatably adjustable position above a free-standing floor-engaging structure. Ear cannula location holes are provided in the cassette holder opposite the back or reverse side of an x-ray exposure aperture. A special beam limiting device is employed simultaneously to minimize patient x-ray exposure and to facilitate rapid accurate relative placement of the usual weight-balanced x-ray source apparatus.
