What role does lead play in an X-ray tube?

Filtration
Collimation
Producing electrons
Converting electrons to X-ray photons

The correct answer is: Collimation

Lead plays a role in collimation in an X-ray tube by shaping the X-ray beam and reducing the amount of scatter radiation that reaches the patient. Filtration is the process of removing low-energy X-ray photons from the beam, while producing electrons refers to the cathode which generates free electrons to interact with the anode. Converting electrons to X-ray photons describes the overall function of the X-ray tube, rather than a specific role for lead. Therefore, lead's role in collimation is the most accurate and specific choice for this question.
