1. Describe X-ray tube operation. Discuss principal components (i.e. cathode, anode, X-ray tube insert, X-ray tube housing).

2. Explain the inverse linear relationship between the number and energy of X-rays produces as seen in an unfiltered, bremsstrahlung spectrum.

3. Explain why low energy X-rays are either not present or lowered in probability in a filtered bremsstrahlung spectrum.

4. Explain why attenuation of lower-energy photons is greater than higher-energy photons.

5. Explain how a small lead collimator reduces off-focal radiation.

6. Explain the concept of beam filtration or beam hardening.

7. Define the following characteristics of the output of an X-Ray system: Quality, Quantity, Exposure, and Production Efficiency.
