Tungsten alloy multi-leaf collimator having a lot of tungsten alloy leaves is used in a medical linear accelerator, to shield radiation, thereby protecting the patients and doctors. According to the experts, it is high density and high strength of tungsten alloy that make it the first choice for radiation shielding applications.

Design of Tungsten Alloy Multi-leaf Collimator
The cross-section of these tungsten alloy leaves must be processed into trapezoidal shapes to eliminate penetrating penumbra in the direction of the vertical multi-leaf movement. The side of these leaves must use a convex groove structure to minimize the leakage dose between adjacent leaves.
Certainly, tungsten alloy can also be used in the capacity of shielding radiation in different medical settings, such as, radioactive source containers, gamma radiography, syringe shields, oncology treatment systems and oncology instruments. In a word, tungsten alloy provides unsurpassed strength, control and protection.
