Which of the following are true with regard to X-ray photon production?
The area of a continuous spectrum graph represents the total output of all X-ray photons emitted as a result of characteristic radiation
Increasing the tube voltage (kV) results in the continuous spectrum shifting to the right and the line spectrum increasing in height
One-quarter of the photons from Bremsstrahlung radiation that reach the patient are less than 20 keV
Increasing the filament voltage causes Bremsstrahlung and characteristic radiation graphs to increase in height
Reducing the filament voltage has no effect on the maximum photon energy produced by characteristic or Bremsstrahlung radiation
