It has been reported that the electron linear accelerator equipped with a tungsten alloy multileaf collimator can make the irradiation field as close as possible to the shape of the tumor, and achieve the purpose of killing the tumor cells to the greatest extent and affecting the normal tissue to the least extent. Generally, tungsten alloy multileaf collimators have unique designs for applying to different electron linear accelerators.

Tungsten alloy multileaf collimator is an important tool for radiation therapy dose delivery. It was originally used as a substitute for lead block field shaping and is now widely used for intensity modulated radiation therapy. You know, tungsten alloy is considered to be the most suitable shielding material for blocking rays. So, there is no doubt that tungsten alloy is used as the material of leaves in multileaf collimator. Certainly, the leakage rate of tungsten alloy leaves of the collimator must meet relevant national standards.
