Radiation Safety Flashcards
1
Q
Photoelectric absorption
A
the energy of incoming x-ray photon is completely absorbed through the ionization of an inner-shell electron of target atom
2
Q
Compton scatter
A
x-ray photon interacts with a target atom’s outer-shell electron, transfer of energy ejects outer-shell electron (ionization), resulting in loss of energy for incident x-ray photon w/ change in direction
3
Q
source-detector distance
A
v - distance from tube to detector
^ - dose
4
Q
focus-to-isocenter distance
A
distance from tube to center of gantry opening
5
Q
focus-to-detector distance
A
distance between tube and detector array
6
Q
tube filtration
A
varies between 6 and 9 mm Al (aluminum)
7

A
