X-Ray Tutor

Front 1

breaking radiation breaks because changes direction when interact with nucleus
• projectile electron (negative charge) comes under influence of the nucleus (electric Coulomb force)
• projectile electron changes direction, varibly
• change in direction causes bremsstrahlung x-ray photon production (conservation of momentum)

bremstrlahlung radiation

Front 2

what constitutes 85% of x-ray photons?

Back 2

bremsstrahlung

Front 3

type of radiaton results when projectile eelctrol collides with a k-shell electron of the target material

electron and x-ray

Front 5

Compton: (scatter) and
photoelectric effect: are interactions of what and what

Back 5

x-rays and matter

Front 6

____ (scatter) comes into patient and is misdirected
______ is when it is good and is completely absorbed

Back 6

Compton: (scatter) photoelectric effect:

Front 7

isotropically:

Back 7

leave x-ray tube in all directions

Front 8

equation of heat units:

Back 8

kVp by mAs (single phase only, x 1.4 for HF)

Front 9

cause by absorption and attenuation of x
x-rays coming off bump into the anode
because some of x-ray is absorbed into anode itself:
this means the beam towards patient will be weak or less intense (anode ) because some x-rays were absorbed.
Cathode: more intense
Intensity of the beam is non-uniform in the long axis of the tube

how to decrease anode heel effect

Back 10

use longer focal fim distances
