and Answers Latest Updated 2026/2027 (Graded A+)
•
indicator number
- ✔✔how much radiation was absorbed into the phosphors
•
image stitching
- ✔✔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
- ✔✔allow the technologist to inset preset text or manual text on the image
•
contrast resolution (digital)
- ✔✔Ability to distinguish anatomic structures having similar subject contrast
•
spatial resolution
- ✔✔Refers to the amount of detail present in any image.Phosphor layer thickness and pixel
size determines resolution in CR.
•
pixel
- ✔✔A single square within a matrix
•
matrix
- ✔✔a series of very small boxes that form a digital image
•
direct conversion
- ✔✔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
- ✔✔component which light enters and is converted into video or electronic signal
•
thin film transistor
- ✔✔used to read charges collected during an exposure
, •
photodiode
- ✔✔A silicon solid state device sensitive to light. Converts light into an electrical signal.
•
scintillator
- ✔✔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
- ✔✔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
- ✔✔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.
•
automatic exposure controll
- ✔✔a device that measures the quantity of radiation that reaches the image receptor and
automatically terminates the exposure when the image receptor has received the required
radiation intensity
•
high frequency generator
- ✔✔, What uses AC and DC power converters to change the incoming line from 60Hz to
6000Hz?
•
three phase generator
- ✔✔...

a single source of ac
•
diode
- ✔✔A device that permits current to flow through it in only one direction
•
rectification
- ✔✔The process of converting AC to DC.
