The beam lighting diaphragms in a simulator are typically made from lead or tungsten due to their properties of high density and effective attenuation of radiation. These materials are essential for controlling the beam, as they help to define the treatment area while minimizing exposure to surrounding tissues. Lead and tungsten are particularly valued for their ability to absorb and scatter radiation, making them ideal for use in applications where precise beam shaping is critical.

In contrast, while aluminum, steel, and plastic may be used in other components of medical equipment, they do not provide the same level of radiation shielding and precision necessary for beam lighting diaphragms. This is why lead or tungsten is the preferred choice for ensuring patient safety and treatment accuracy in radiation therapy simulation.
