X Ray Production

Question 1

How are the X-Ray Photon produced?

Answer 1

-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

Question 2

What is quantity (intensity)?

Answer 2

x ray beam refers to the number of x ray photons

Question 3

what is the prime controller of quantity?

Answer 3

mAs

Question 4

what is quality ?

Answer 4

is the energy or penetrating ability of the x ray beam

Question 5

what is the prime controller of quality?

Answer 5

kVp
Also can influnce the number or quantity of the beam

Question 6

Increasing the mAs will cause an…

Answer 6

increase in the number of electrons

Question 7

Decreasing the mAs will cause a…

Answer 7

decrease in the number of electrons

Question 8

What does the mAs and quantity show?

Answer 8

A direct relationship between mAs and quantity

Question 9

What does kVp have NO EFFECT on

Answer 9

the number of electrons but the speed of the electrons

Question 10

What does increasing the kVp do?

Answer 10

Increases potential difference between the anode and cathode

Question 11

After increasing the POTENTIAL difference between the anode and cathode what else increases ?

Answer 11

the kinetic energy
speed of electrons
the number of interactions (occur in anode)
number and energy quality of photons produced

Question 12

mAs has NO EFFECT on..

Answer 12

the speed of the electrons

Question 13

Answer 13

half of speed of light

Question 14

photons are…

Answer 14

the speed of light

Question 15

what does the spectral distribution/Emission spectrum indicate ?

Answer 15

the number of x ray photons and their energies
