Question 1
In X-ray production, which interaction mechanism accounts for the continuous spectral distribution of emitted photons from a tungsten target?
Correct Answer:
Bremsstrahlung radiation
Question 2
What primary effect does adding aluminum filtration to a diagnostic X-ray tube housing have on the emitted X-ray beam?
Correct Answer:
It increases beam quality by absorbing low-energy X-ray photons
Question 3
The probability of photoelectric absorption per unit mass is proportional to which relationship involving the atomic number (Z) of the absorber and photon energy (E)?
Correct Answer:
Proportional to Z^3 / E^3
Question 4
Which interaction between X-ray photons and matter dominates in soft tissues at photon energies between 30 keV and 30 MeV?
Correct Answer:
Compton scattering
Question 5
In Computed Tomography (CT), how is the Hounsfield Unit (HU) of a tissue with linear attenuation coefficient μ_tissue defined relative to water (μ_water)?
Correct Answer:
HU = 1000 × [(μ_tissue - μ_water) / μ_water]
