ANSWERS {2025}
Indicator number - ACCURATE ANSWERS✔✔ how much radiation
was absorbed into the phosphors
Image stitching - ACCURATE ANSWERS✔✔ 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 - ACCURATE ANSWERS✔✔ allow the technologist
to inset preset text or manual text on the image
Contrast resolution (digital) - ACCURATE ANSWERS✔✔ Ability to
distinguish anatomic structures having similar subject contrast
Spatial resolution - ACCURATE ANSWERS✔✔ Refers to the amount
of detail present in any image.Phosphor layer thickness and pixel size
determines resolution in CR.
Pixel - ACCURATE ANSWERS✔✔ A single square within a matrix
, Matrix - ACCURATE ANSWERS✔✔ a series of very small boxes that
form a digital image
Direct conversion - ACCURATE ANSWERS✔✔ 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 - ACCURATE ANSWERS✔✔ component
which light enters and is converted into video or electronic signal
Thin film transistor - ACCURATE ANSWERS✔✔ used to read charges
collected during an exposure
Photodiode - ACCURATE ANSWERS✔✔ A silicon solid state device
sensitive to light. Converts light into an electrical signal.
Scintillator - ACCURATE ANSWERS✔✔ 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.
