New cards

photon passes through pts atom, hits nothing, atoms unchanged

No interaction

2

New cards

Photons hit receptor + energize silver halide crystals

No interaction

3

New cards

Best interaction

No interaction

4

New cards

NO ionization or scatter radiation

No interaction

5

New cards

Photon hits no e^- misses nucleus

No interaction

6

New cards

Total transfer of energy from x-ray photon to atoms of matter the x-ray beam produces

Absorption

7

New cards

Photon dislodges inner orbit e^-

Absorption/photoelectric effect

8

New cards

Ionization occurs; photon hits inner e^- and gives up all energy to eject it

Photoelectric effect

9

New cards

Loses ALL energy b/c it’s working to eject an inner orbit e^-

Absorption/photoelectric effect

10

New cards

In the photoelectric effect, what happens to the ejected e^-

It is absorbed by other atoms

11

New cards

photon completely absorbed by atom it hit; no further radiation

Absorption/photoelectric effect

12

New cards

Doesn’t travel any further to interact w/ more atoms

Absorption/photoelectric effect

13

New cards

Accounts for 30% of interactions

Absorption/photoelectric effect

14

New cards

Photon hits outer shell e^- and gives up some energy to eject it

Compton scatter

15

New cards

62% of interactions

Compton scatter

16

New cards

Photon is slower and bounces off another direction and may interact w/another atom

Compton scatter

17

New cards

Ejected e^-

Compton e^-

18

New cards

Photon’s path changes and slows down, continues on

Compton scatter

19

New cards

X-ray photon that has its path altered while passing through an outer shell e^- orbit

Coherent scatter

20

New cards

No e^- ejected/photon doesn’t hit e^-

Coherent scatter

21

New cards

Orbit changes photons path as it travels next to atom

Coherent scatter

22

New cards

No energy loss, just a detour

Coherent scatter

23

New cards

8% of interactions

Coherent scatter

a, no interaction

28

New cards

A form of secondary radiation and is the result of an X-ray that has been deflected from its path by the interaction with matter

Scatter radiation

29

New cards

Penetrating x-ray beam that is produced at the target of the anode and that exits the tubehead

Primary beam

30

New cards

X-radiation that is created when the primary beam interacts with matter

Secondary beam
