Lmrt state review Exam 2026 Questions
and 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
density - Correct answer-It is the degree of blackening of a radiograph resulting
from radiation exposure and processing and one of the two photographic properties
that comprise visibility of detail.
