Lmrt state review; Verified Questions
& Answers.
indicator number ~CORRECT ANSWER~✓✓how much radiation was
absorbed into the phosphors
image stitching ~CORRECT ANSWER~✓✓stitching together multiple
images - useful for scoliosis studies of the spine, long bone studies or
angiographic imaging of peripheral vasculature. - to view as a single
image.
image annotation ~CORRECT ANSWER~✓✓allow the technologist to inset
preset text or manual text on the image
contrast resolution (digital) ~CORRECT ANSWER~✓✓Ability to
distinguish anatomic structures having similar subject contrast
spatial resolution ~CORRECT ANSWER~✓✓Refers to the amount of detail
present in any image.Phosphor layer thickness and pixel size determines
resolution in CR.
pixel ~CORRECT ANSWER~✓✓A single square within a matrix
, matrix ~CORRECT ANSWER~✓✓a series of very small boxes that form a
digital image
direct conversion ~CORRECT ANSWER~✓✓one step process in DR where
flat panel detectors convert the x-ray energy directly to an electric signal
using an amorphous selenium detector for immediate viewing
charged coupled device ~CORRECT ANSWER~✓✓component which light
enters and is converted into video or electronic signal
thin film transistor ~CORRECT ANSWER~✓✓used to read charges
collected during an exposure
photodiode ~CORRECT ANSWER~✓✓A silicon solid state device sensitive
to light. Converts light into an electrical signal.
scintillator ~CORRECT ANSWER~✓✓Amorphous silicon requires a _____
such as cesium iodide or a rare earth intensifying screen composed of
gadolinum and lanthanum with oxysulfides. This also converts x-rays to
visible light.
flat panel detector ~CORRECT ANSWER~✓✓a type of digital detector
employing amorphous silicon or selenium detector material, bonded with
thin-film transistor technology for digital image creation and amplification
