Compton Effect
Photoelectric Effect
2
Q

A
scatter has equal energy incident photon
3
Q
Compton effect
A
compton scatter is the most common mechanism of scatter production in human tissue
4
Q
Photoelectric Effect
A
same basic process as characteristic radiation production, except that characteristic radiation is caused by electron smashing into electrons while photoelectric effect is caused by photons smashing into photons
5
