Update | 100% Correct.
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
