Portable roentgenographic cephalostat

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 the mid-sagittal plane of the patient's head; and a dial 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.
