Factors affecting x ray emission Flashcards
in X-ray, quantity is…
number of x rays in the beam
in X ray, quality is…
Penetrability of the beam
Filtration is removal of _______ x rays from the useful beam with ______ or other metal
low-energy, aluminum
when you filtrate, it gives you 3 things, what are they?
X ray beam with higher energy, greater penetrability, and better quality
what is half value layer?
thickness of absorber or homogenous filter that will reduce an x ray beam to half of its original value
x rays with high penetrability are termed….
high quality / hard x rays
low penetrability x rays are called
low quality / soft x rays
when the energy of the x ray beam increased, so does
the penetrability of x ray beam
why does kVp has more effect on exposure than any other factor?
b/c it affects the quality and to a lesser degree influences beam quantity as well
does mAs have effect on beam quality?
no
When changing mA, what does it affect?
quantity of X rays
if you change mA(s), it affects …
exposure rate which is equal to quantity
when you send more (A)mp in the mAs, what are you dealing with?
sending more numbers of electrons
increasing kVp means…
higher energy x rays
Do patient receive more absorption in high penetration?
no, patient receive less absorption in high penetration because it travels through the patient.
