analog to digital converter
positive electrode in the x-ray tube
anode
PBL
positive beam limitation
holds cassette or image plate
bucky
light proof container holds film or digital plate
cassette
negative electrode in x-ray tube
cathode
limits x-ray beam to specific area of the body
collimator
the difference in densities
contrast
computed radiography digital imaging using cassette
CR
CRT
cathode ray tube (video monitor)
digital imaging & communication used in pictures and communication/health level 7 used in transfer or electronic information
DICOM-HL7
direct digital radiography - uses fixed detectors to produce image without a digital cassette
DR
degree of darkness on an image
density
misrepresentation of size and/or shape of an object being radiographed
distortion
it is a number produced which tells the status of a digital image
exposure indicator (EI)
is prior to being exposed to radiation
film
area of the anode from which x-rays emanate
focal spot
moves and helps remove scatter radiation from an image
grid
HIS
health information system
it is a graphic display of the exam pixel values formed in the image
histogram
device that absorbs x-rays after having passed through the patient
image receptor (IR)
Made of photostimulable phosphor that absorbs the photons that exit the patient, it is inside
a CR cassette
imaging plate (IP)
Mounted in a film screen cassette either single or paired they glow when exposed to
radiation which in turn exposes the film
intensifying screen
kVp
kilovoltage peak
determines the wavelength of the of the x-ray beam and
determines the contrast of the image
