What is the primary benefit of using lead or tungsten for beam lighting diaphragms in simulators?

The primary benefit of using lead or tungsten for beam lighting diaphragms in simulators is their durability and effectiveness in radiation shielding. Both lead and tungsten possess high atomic numbers and density, which makes them particularly effective at absorbing and attenuating radiation.

In radiation therapy, controlling the direction and intensity of the beam is crucial for maximizing the dose to the tumor while minimizing exposure to surrounding healthy tissue. The materials used in beam lighting diaphragms must be able to withstand the intense radiation while providing precision in beam shaping. Lead and tungsten fulfill this requirement due to their robust shielding properties, ensuring that the radiation does not leak and that the precision of the treatment plan is maintained.

Additionally, their durability means that they can withstand repeated use without degradation, which is essential for maintaining consistent performance in clinical settings. These properties make lead and tungsten the ideal choices for effective and safe beam lighting diaphragms in simulators.
