Craniostatic positioner, particularly for the ambulatorial radiography of the temporal-mandibular articulation

A craniostat, particularly for the ambulatorial radiography of the temporal-mandibular articulation, characterized in that it comprises a cantilevered stand or support carried for controlled height adjustment at the end of a columnar upright rigid with a seat, a supporting pivot pin carried by a slider arranged to be slidable on the horizontal arm of said cantilevered stand and subjected to controlled displacement parallel to said arm, a transverse yoke carried by said pivot pin for angular oscillation in the vertical plane containing said yoke, a pair of plates carried at the ends of said yoke and enabled to controllably move parallel to the axis of said yoke and rotate about said axis, one of said plates carrying at the free end thereof a collimator with a socket for the insertion of the X-ray tube therein, the other of said plates carrying at the free end thereof a cassette holder provided with a luminous centering device set coaxially to said collimator, and a means for positioning the patient's head relatively to the craniostat including a headrest and a forehead slider, both said headrest and said forehead slider being adjustable, as well as an auricolar compass provided with at least one swivelling extension adapted for cooperating with the patient's auricolar cavities in defining a reference plane containing anatomically definite and selectable points of the patient's cranial structure.
