Control of the endpoint of decalcification by fluoroscopy.

Abstract

AbstactThe control of the endpoint of decalcification of histological specimens can be done by X-ray fluoroscopy. An X-ray machine is mounted under the table in the laboratory. A leaden tube leads from the X-ray machine and is closely adapted to a hole in the table. The opening on the table surface is covered with a 5 mm. thick plastic plate on which is placed the object to be examined. The object is observed in a regular fluoroscope. All precautions to prevent direct and indirect X-ray irradiation of the observer should be taken.
