Text Appearing After Image:
Plate 14.—Head-rest for Ophthalmic Radiographs. Authors duplicate of DavidsonsHead-rest for fixing the plate and head during exposures for localization of foreign body inthe eye. To hold the head with absolute fixation while making two radiographs of the eyeDavidson devised a head-frame which serves the purpose exactly. It is made stoutly of liardwood. The one in possession of the author is mahogany, and has a right and left side. Thephotograph shows it very imperfectly. A 5 x 7 plate fits in either side window. A chin-clampfixes the head immovably in the desired position. This is one of the great advantages of theappliance. A sliding tube-carrier takes a tube in a fixed relation to the eye exposed. A scaleon the arm measures the side displacement when stereoscopic radiographic pictures are made,and to facilitate stereoscopic exposures was one of the chief reasons for making the frame.The surgeon dealing with the localization of foreign bodies in the eye will find it indispensable.I
