A device for assisting a fluoroscope operator in orienting a fluoroscope on an object during a fluoroscope examination, and thereby reduce the time of use and exposure to radiation, which device consists of a sheet transparent to x-ray radiation, preferably disc shaped, possessing orientation indication means, such as radiopaque symbols, numbers and letters which may be combined in any combination. The orientation device is mounted on the fluoroscope's receiver, thereby positioning the sheet and orientation indicators between the receiver tube and the object being examined. The orientation indicators are visible on the fluoroscope's monitor, clearly indicating direction and providing guidance for the fluoroscope operator during the examination.
