ABSTRACT:
An improved cephalostat comprising an upper housing portion and rotatable lower housing portion wherein a patient's head may be positioned below the lower housing portion and lateral, anterior, posterior, or frontal oblique, x-ray pictures may be selectively taken. Said lower housing portion includes a gear and gear rack assembly for the relative positioning of associated earposts and a top knob adjustment for the earposts extends outward from the top of the upper housing portion. The upper housing portion further accommodates adjustable support rod means for an x-ray cassette holder that is held laterally to one side of the upper housing portion. The lower housing portion is capable of accommodating support slide rods which carry a nasion positioner. The improved cephalostat further includes indexing holes through the top wall of the upper housing portion covered thereover by a rotatable index plate means having an index hole and pin whereby the pin may be selectively positioned into a chosen index hole of the top wall for locking the lower housing portion in a chosen rotational alignment. The cephalostat also includes a vertically and horizontally adjustable film cassette holder. The two housing portions are completely separable for maintenance and adjustment. The cephalostat may also include detachable supports for demountable attachment to a wall mounting plate.
