ABSTRACT:
A portable cephalostat is shown as having a frame-like base subassembly which provides for an area upon which a patient's head is to rest and a support for supporting locating arms which serve to locate the patient's head in a selected position; the base subassembly provides for the placement of a first film, to be exposed, below the patient's head and for the placement of additional film, also to be exposed, generally to one side of the patient's head and generally parallel to and spaced a first distance from the mid-sagittal plane of the patient's head; provision is also made for the placement of other film, also to be exposed, generally to the same one side of the patient's head and generally parallel to and spaced a second distance from the mid-sagittal plane of the patient's head; further provision is made for the placement of still further additional film, to be exposed, generally transverse to the patient's head and spaced from the top thereof; an indicator is provided for, upon attaining the desired location of the patient's head, automatically indicating the elevation of the axis of the patient's auditory canals with respect to the first film; and certain elements are made to be foldable to conserve space and assist in the transportation of the cephalostat.
