Which of the following best describes the function of lead in the tubehead?

Lead in the tubehead mainly acts as a shield and beam-limiting device. Its job is to shape the X-ray beam with a lead collimator so that the radiation is confined to the size of the receptor, which reduces the patient’s dose and minimizes exposure to the operator and surrounding tissues. The other components have different roles: insulating oil helps cool and insulate the tube, aluminum disks filter out low-energy photons, and the X-ray tube is the source that generates the rays. So the best description of lead’s function is that it serves as a lead collimator to define and restrict the beam.
