Which of the following are components of a typical collimator?

Explanation:
A collimator visualizes and shapes the x-ray beam by using a light source and a mirror. The light bulb provides the illumination, and the mirror reflects that light so you can see the field on the patient side, ensuring the x-ray field matches what you intend to irradiate. Rare earth phosphor is used in other components like scintillation screens, not in the collimator itself. So the combination that fits a typical collimator is the mirror and the light bulb.
