Collimator - ANSWER: a box-shaped device attached to the bottom of the tube
housing
collimator purpose - ANSWER: restricts the x-ray beam to the area of interest of
the body and to help localize the beam to that area
Film-screen cassette - ANSWER: Serves as a container for both the intensifying
screens and the film
film-screen cassettes must be - ANSWER: -light-proof
-lightweight for portability
-rigid enough not to bend under a patients weight
all while allowing the maximum amount of radiation to pass through and reach the
screens
low x-ray absorbing materials such as
_______________________________________________________ can be found
inside the fronts of film-screen cassettes - ANSWER: thermostat plastic,
magnesium, or graphite carbon fiber
,2|Page
Inside the backs of film-screen cassettes may be found - ANSWER: thin sheets of
lead foil designed to absorbed backscatter before it exposes the film
A CR cassette houses the - ANSWER: imaging plate (IP)
In CR cassettes, radiation exiting the patient interacts with the
__________________________ where the photon intensities are
____________________ by the phosphor - ANSWER: imaging plate (IP),
absorbed
In CR cassettes, although some of the absorbed energy is released as
_______________ _________________ (luminescence), a sufficient amount of
energy is stored in the ________________ to produce a ____________
_____________. - ANSWER: visible light, phosphor, latent image
luminescence - ANSWER: emission of light when stimulated by radiation
in CR cassettes, the imaging plate (IP) consists of - ANSWER: support, phosphor,
and protective layers
in CR cassettes, the phosphor layer is composed of
______________________________________ which is referred to as the
______________________ - ANSWER: barium fluorohalide crystals doped with
europium, photostimulable phosphor (PSP)
in CR cassettes, the photostimulable phosphor (PSP) emits visible light when
stimulated by a high-intensity laser beam, a phenomenon termed - ANSWER:
photostimulable luminescence
, 3|Page
CR imaging requires a two step process for image acquisition - ANSWER: image
capture in the IP and image readout
in a CR cassette, the latent image is formed in the ________ when the exit x-ray
intensities are absorbed by the phosphor and the europium atoms become ionized
by the photoelectric effect - ANSWER: PSP
in CR cassettes, exposed IPs should be processed within a relatively short amount
of time (within 1 hour) because the latent image _________________ -
ANSWER: dissipates over time
the CR latent image is acquired in the _________ layer of the IP. Most energy from
the exit radiation intensities is stored in the PSP for extraction in the reader unit -
ANSWER: PSP
In CR cassettes, the imaging plate (IP) is exposed to a
__________________________________________ to release any residual energy
that could effect future exposures - ANSWER: bright white light
In a CR cassette, PSPs can be reused and are estimated to have a life of
_________________ readings before requiring replacement - ANSWER: 10,000
DR image receptors have a self-scanning readout mechanism that employs an array
of x-ray detectors that receive the exit radiation and convert the varying x-ray
intensities into proportional electronic signals for - ANSWER: digitization
DR imaging ___________ the two processes of image capture and image readout -
ANSWER: combines
