Tungsten heavy alloy multileaf collimator is composed of some individual tungsten alloy leaves, which can move independently in and out of the path of a particle beam. Multileaf collimator is a crucial device on a medical electron linear accelerator that directs a beam and focuses radiotherapy treatment to obtain precisely conformed shapes, thereby delivering correct therapy doses to patients. Multileaf collimators are widely used in radiology departments and are an integral part of radiotherapy.

It has been reported that the application of high density tungsten heavy alloy multileaf collimator makes the linear accelerator a true tumor nemesis as it can accurately guide radiation to kill cancer cells, while providing comprehensive radiation protection for healthy cells. Tungsten alloy multi-leaf collimator, which is mainly made by precisely processing a tungsten-based alloy with excellent shielding effect and good processing performance, moves accurately under the control of computer automation to achieve the effect of conformal radiotherapy.
