6 Flashcards
spectrum that contains only specific values
discrete spectrum
spectrum that contains all possible values
continuous spectrum
refers to the range of values of any quantity such as x-rays.
spectrum
plot of the frequency with which characteristic x-rays are emitted as a function of their energy
Characteristic X-ray Spectrum
discrete energies of characteristic x-rays
binding energy
Characteristic x-rays have precisely fixed (discrete) energies and form a discrete emission spectrum.
(no answer)
fixed energies
If it were possible to measure the energy contained in each bremsstrahlung x-ray emitted from an x-ray tube, one would find that these energies range from the peak electron energy all the way down to zero.
bremsstrahlung x-ray spectrum
Bremsstrahlung x-rays have a range of energies and form a continuous emission spectrum.
(no answer)
range of energies
shape of the bremsstrahlung x-ray spectrum
same for all x-ray imaging systems
maximum energy (in keV) of a bremsstrahlung x-ray is equal to
kVp
number of x-rays emitted decreases rapidly at very low
energies
low energy = low no. of x-ray emitted
