Medical accelerator is a kind of Particle accelerator in biomedical for radiation therapy of tumors. At present, the tungsten alloy linear accelerator is the most widely used in radiotherapy in the world.

Tungsten alloy linear accelerator uses high frequency electromagnetic field to accelerate, and the acceleration of the particle trajectory is a straight line. The high-frequency linear accelerator, short for linear accelerator, refers to a device that accelerates charged particles by using a high-frequency electric field distributed along a linear orbit. Tungsten alloy electron linear accelerator uses the interaction between the high-energy electrons (subvelocity of light) with certain energy and microwave electric field with high power microwave to get more energy. 

 

 

Tungsten alloy linear accelerator is powerful, but its radiation in treatment cannot be underestimated. Inside the radiation head, besides the uniform filter that has a shield to uniformly distributing the X- radiation, there is a scatter filter with several shields to evenly distribute the electron radiation. In order to regulate the electron radiation field, it’s necessary to add tungsten alloy beam limiting shielding devices with different sizes and shapes when during the electronic radiation treatment. An electronic linear accelerator made of tungsten alloy material has the characteristics of environmental friendly.

 

Tungsten alloy material has high density and reduces the size of the radiation shield without affecting the ray shielding effect. Radiation detectors made from tungsten alloys are harmless. Tungsten alloy linear accelerator is widely used for primary or secondary tumors in the neck, chest, abdominal cavity, pelvic cavity and limbs, as well as the residual postoperative or preoperative surgical treatment.
