Abstract

Two Practical Radiologic Suggestions William Robert Stecher , M.D. Department of Radiology of the Fitzgerald-Mercy Hospital Darby, Pennsylvania Excerpt Due to economic considerations, many institutions unfortunately find themselves unable to purchase special viewing boxes for operating room purposes; and since large windows are customarily an integral part of most operating rooms, the roentgenograms to be examined are usually fastened against the window pane, by means of adhesive plaster tabs, and thus illuminated by the transmitted daylight. This procedure is patently not applicable for viewing wet roentgenograms, which necessity not infrequently arises. The manifold disadvantages of the current method have been successfully eliminated since adopting the inexpensive contrivance to be described below. A coat-hanger appliance equipped with a rubber suction pad can be purchased for a small sum.
