Question 1
Which interaction between X-ray photons and tissue is most responsible for the diagnostic subject contrast seen between bone and soft tissue at typical radiographic energies?
Correct Answer:
Photoelectric absorption
Question 2
An X-ray beam passes through a slab of tissue equal to three half-value layers (HVL). What fraction of the original beam intensity remains?
Correct Answer:
1/8
Question 3
Bremsstrahlung ("braking") radiation in an X-ray tube is produced when:
Correct Answer:
An incident electron is decelerated in the electric field of a target nucleus
Question 4
A tungsten X-ray tube target produces characteristic K-shell radiation. This occurs because:
Correct Answer:
An incident electron ejects a K-shell electron and an outer-shell electron fills the vacancy, releasing energy equal to the binding energy difference
Question 5
An X-ray tube operating at a peak potential of 90 kVp produces a bremsstrahlung spectrum. What is the maximum possible photon energy in this beam?
Correct Answer:
90 keV
