positive electrode of the x-ray tube

grid that is an integral part of the x-ray table, located below the tabletop and above a cassette tray; decreases the amount of scatter radiation reaching the image receptor, which increases contrast; moves during exposure so that no grid lines appear on the image

light-proof holder for the image receptor; for computed radiography, the cassette holds the reusable photostimulable phosphor imaging plate; for conventional film-screen radiography, the cassette contains intensifying screens and a sheet of film

negative electrode of the x-ray tube

diaphragm or system of diaphragms made of an absorbing material; designed to define the dimensions and direction of a beam of radiation

device used for dynamic radiographic examinations; usually consists of an x-ray tube situated underneath the x-ray table and an electronic image intensifier situated over the x-ray table

examination by means of the fluoroscope

lengthwise; along the long axis

equipment that permits the acquisition of static images during a dynamic fluoroscopic examination

placed crosswise; situated at right angles to the long axis of a part

pivoting the tube at the point where it is attached to its support

perpendicular to the plane of the horizon

device that produces x-rays
