Product Description

Why Need Tungsten Alloy Multi-leaf Collimator?

When people undergo the cancer or the tumor treatment, numerous hospitals primarily employ CT simulation system for images gathering and patient respiratory motion analysis, and then radiation therapy is needed. Tungsten alloy multi-leaf collimator is basically used for saving patients from unwanted radiation.

As we know, tungsten heavy alloy can offer the same energy concentration as lead using 1/3 less material, besides, it is eco-friendly, higher density from 17.0 g/cm3 to 18.6 g/cm3 make tungsten alloy multi-leaf collimator highly effective for radiation absorption, as it is dense enough to soak radiation from the radiation therapy machine as to make patient safe.


How is Tungsten Alloy Multi-leaf Collimator Radiation Ability?

As compared to old-type radiation shielding materials like boron carbide and lead, Tungsten Alloy features higher density with less capacity. With the similar weight, better-density alloy can give the same-level energy absorption with being thinner than any other material, tungsten alloy is a preferred material for something that requires better radiation absorption and offers very small space.

KJ Tungsten does not only offer tungsten alloy collimator in compliance with the global standard, but also custom-designs tungsten alloy collimator according to clients requirement. Usually, radiation ability can be assessed based on the following formula:


Formula :

  • K = e0.693 d / 1/2
  • K : Shield weakened multiple
  • 1/2 : The protecting material of the half-value layer

D : Protective thickness, with the half-value layer thickness of their units, people require half-value layer thickness for changing into the thickness of the material, division into the density of the material can be achieved.


How Tungsten Alloy Multi-leaf Collimator to Make Radiation Protection

In accordance with the Lesion target period of the motion, in the permitted setting array of motion, radiation ray beam from the machine sets off automatically, on and off, in order to regulate the movement of the couch, subsequently it coincides with the movement of tumor (target), thus ensuring a real-time dynamic accurate radiotherapy. This method is relevant to the treatment with the movement effected by respiratory motion in a greater degree of lung, liver, breast, etc. The entire process for treatment of tumors or cancer, including abdomen and chest, is supported by an infrared that tracks the motion of the surface reflection markers, through surface infrared reflective markers, making use of fluoroscopic image for conducting the verified treatment of disease, this would create a certain radiation of the radioactive material. If there is no high-efficieny material of radiation shielding as tungsten alloy collimator for the production of the treatment device, then other parts of the patient is meanwhile exposed to radiation damage. It will be terribly harmful. Therefore, when the radiation disperses, tungsten alloy multi-leaf collimator can effectively soak radiation to save the patient.
