Ans: source of electrons that are negatively charged and contain a filament that is
heated and spews off electrons
anode
Ans: attracts the electrons at a great speed. the "accelerator"
pyrex glass tube
Ans: surrounds the anode and cathode and maintains a vacuum which prevents air from
interfering with the traveling electrons
scatter
Ans: x-ray hits patient but does not enter tissue. new photon of lower wave length that
travels in a different direction. source of fog on radiograph and source of useless
radiation to patient
absorption
Ans: some/all of x-ray energy absorbed by tissue. removes photons from beam, results
in white areas on image - metallic restorations, cortical bone/enamel.
