RTE 1401 Exam 3 Prep Questions
and Answers Latest Version 2026
A loss of contrast due to noise is known as
scatter
If you wanted to alter the scale of contrast you must adjust
______
kVp
radiographic quality =
kVp
Variations of shades of gray are necessary to provide
_________
contrast between various anatomical structural images
If the beam is mainly absorbed by the patient, in turn never
hitting the IR, this is because
kVp is too low aka useless.
More SID means?
less exposure
Less SID means?
more exposure
What are some factors that will result in sn increase in
receptor exposure?
Any time you see receptor exposure it means the number of
________ ?
x-rays
What side of the xray do the feet and thicker portions go to?
cathode. FAT CAT
quantum mottle does what to xray?
unwanted noise, fog, decreases contrast
Radiographic exposure and SID have a ________ type of
relationship?
inverse.
TRUE OR FALSE -> kVp and quality is the same.
, true
Another word for mAs would be ____
wuantity
penetrability is also known as ?
kVp (quality)
TRUE OR FALSE --> intensity, exposure, and quantity are all
the same word.
true
HVL (half value layer) is ?
filtration.
exposure = _____
mAs
the number of xrays in the useful beam defines the xray
__________
quantity
if xray quantity is doubled, the exposure on the finished
radiograph will be ________
doubled
the inverse square law has the same effect on exposure and
xray ________
the penetrability of an xray beam is called x ray _______
quality
HVL of an xray beam is the measurement of beam ________
filtration
exposure on a radiograph is primarily the result of
controlling what?
mAs

yield a radiograph that is considered to have
Low contrast
Bremsstrahlung interactions may occur only when the
indigent electrons interact with
the force field of the nucleus
