Archive historical; films with archive value will not diminish in quality over time; archive quality is affected by processing and film age Artifact a blemish or image in the radiograph that is not present in the actual object Atom the smallest particle of an element that has properties of that element. Atoms are extremely minute and are composed of a number of subatomic particles Barrier Envelope Packet clear, plastic "baggie" that film can be placed in during exposure; prevents film from becoming contaminated with saliva Barriers any material that is used to prevent the transmission of infective pathogens Central rays (CR) the central portion of the primary beam of radiation Cephalometric lateral and posteroanterior extraoral head films Cephalostat a device used to stabilize the patient's head in a plane that is parallel to the film and at right angles to the central rays of the x-ray beam Charged-coupled device a CCD is a solid-state detector used in many electronic devices. A CCD used in radiography is an image receptor found in the intraoral sensor, which converts x-rays into electrons Chronic exposure low level exposures to radiation over a long period of time Collimator a diaphragm, usually lead, designed to restrict the dimensions of the useful beam; looks like a lead washer Cone cut term used to describe a blank area on a radiograph where the PID (position indicating device) did not cover the entire film Contrast the visual differences between shades ranging from black to white in adjacent areas of the radiographic film; increased kilovoltage results in the production of a radiograph with a long-scale contrast (many variations in shade)

Control panel section of the x-ray machine that houses the timer, milliammeter, and kVp selector Convex outward even curve Coulombs/kg a unit of electrical charge; measurement of radiation exposure in air Daylight loader a light-shielded compartment attached to an automatic processor so films can be unwrapped in a room with white light Definition the sharpness and clarity of the outline of the structure on the image shown on the film Density film blackening (the amount of light transmitted through a film); the simplest way to increase or decrease the density of a radiograph is to increase or decrease the milliamperage and exposure time Detail the point-by-point delineation of the minute structures visible in the shadow images on the radiograph; sharpness or how well the smallest details of an object are reproduced on a dental radiograph Digital imaging a method of making a radiographic image using a computer Disinfect a term used to describe those efforts made to reduce the disease-producing microorganisms to an acceptable level Dose equivalent a term used for radiation protection purposed to compare the biological effects of the various types of radiation. Measured in rems and sieverts Edentulous without teeth; areas of the jaw with no teeth Electron a small negatively charged particle of an atom containing much energy and little mass; electrons are found in orbits around the nucleus Exposure a measurement of ionization produced in ait by x-ray or gamma radiation: the units of measurement for exposure are the Roentgen and coulombs/kg Extension arm flexible arm from which the tube head of the x-ray machine is suspended; houses wires that connect the tube head and the control panel
