Technology Review Flashcards
sudden deceleration as electrons collide with target anode
Bremsstrahlung X-rays
void filled by outer shell electron with emmision of single X-ray photon
characteristic radiation
low energy x-ray photon removes atomic electron
photoelectric effect/absorption
radiopaque
obstructs transmission
radiolucent
permeable to radiation
difference between radiopaque and radiolucent areas
contrast
differential absorption increases as
kVp goes down
attenuation
radiation loses power with penetration
cathode expels electrons using heat
thermionic emission
focal spot
x-ray producing part of anode
x-rays at cathode end of tube have more intensity
anode heel effect
mAs
quantity or density
kVp
quality or contrast
higher the kVp
lower the contrast
half value layer
material used to half x-ray
