n.
historically, an instrument by which X-rays were projected through a patient onto a fluorescent screen enabling the resultant image to be viewed directly by the radiologist. However, this resulted in high radiation doses for the radiologist. For diagnostic purposes the screen has been replaced by the image intensifier and TV monitor.
