The characteristic most often used to describe the energy of an X-ray

beam is its:

• velocity
• space charge
• wavelength
• amplitude - ANSWER-c. wavelength

grid cap - ANSWER-A grid mounted in a frame that can be attached to the front of an image receptor (IR) for mobile radiography and other special applications.

An X-ray beam that has been attenuated by matter is called

• remnant radiation
• primary radiation
• secondary radiation 1 / 4

pg. 2

• scatter radiation - ANSWER-a. remnant radiation

image intesifier - ANSWER-An electronic device used to produce a fluoroscope image with a low radiation exposure. A beam of x-rays passing through the patient is converted by a special vacuum tube into a pattern of electrons. The electrons are accelerated and concentrated onto a small fluorescent screen, where they present a bright image that is usually displayed on a television monitor.

A device used to indicate the location of the radiation filed and to control

its size is called a:

• grid
• collimator
• transformer
• control console - ANSWER-b. collimator

image receptor (IR) - ANSWER-A device that changes the x-ray beam into a visible image. An image receptor may be a radiographic film and cassette, a phosphorescent screen (used in fluoroscopy or computed radiography), or a special detector placed in a table or upright bucky diaphragm (used in direct digital radiography).

An X-ray machine that permits viewing of the X-ray image in motion in

real time is called a: 2 / 4

• control console
• fluoroscope
• collimator
• buckey - ANSWER-b. fluoroscope

latent image - ANSWER-The unobservable image stored in the silver halide emulsion of film; it is made visible by processing.

The prime factor controls the wavelength of the x-ray beam is:

• milliamperage
• exposure time
• kilovoltage
• object-image distance - ANSWER-c. kilovoltage

photon - ANSWER-The smallest quantity of electromagnetic energy. It has no mass and no charge and travels at the speed of light. Photons can occur in the form of light rays, x-rays, gamma rays, and other electromagnetic energies.

photostimulable phosphor - ANSWER-Crystals that store the energy of the remnant x-ray beam and release it as light when stimulated by a laser. 3 / 4

pg. 4

The four prime factors of radiographic exposure are exposure time,

milliamperage, kilovoltage, and:

• optical density
• source-image distance
• object-image distance
• image detail - ANSWER-b. source image distance

The prime factor that controls the rate at which x-rays are produced is:

• exposure time
• kilovoltage
• milliampere-seconds
• milliamperage - ANSWER-d. milliamperage

The image system that provides an instantaneous digital image on a

monitor is called:

• digital radiography
• computed radiography
• film-screen radiography
