X Ray Production Flashcards
How are the X-Ray Photon produced?
-High speed electrons from the cathode (incident electrons) strike the anode target
-Electrons transmit kinetic energy to the atoms of the target material
-Photons produced and mitted isotropically
What is quantity (intensity)?
x ray beam refers to the number of x ray photons
what is the prime controller of quantity?
mAs
what is quality ?
is the energy or penetrating ability of the x ray beam
what is the prime controller of quality?
kVp
Also can influnce the number or quantity of the beam
Increasing the mAs will cause an…
increase in the number of electrons
Decreasing the mAs will cause a…
decrease in the number of electrons
What does the mAs and quantity show?
A direct relationship between mAs and quantity
What does kVp have NO EFFECT on
the number of electrons but the speed of the electrons
What does increasing the kVp do?
Increases potential difference between the anode and cathode
After increasing the POTENTIAL difference between the anode and cathode what else increases ?
the kinetic energy
speed of electrons
the number of interactions (occur in anode)
number and energy quality of photons produced
mAs has NO EFFECT on..
the speed of the electrons
Electrons are ..
half of speed of light
photons are…
the speed of light
what does the spectral distribution/Emission spectrum indicate ?
the number of x ray photons and their energies
