Tungsten alloy pre-patient collimator is the tungsten alloy collimator located in front of the X-ray tube on a CT machine, with characteristics of high density, smooth surface and good dimensional accuracy. Tungsten alloy pre-patient collimator is the first component through which X-rays pass, and is mainly used to control the thickness of the scanning layer by controlling the width of the X-ray beam in the direction parallel to the long axis of the human body. The X-rays emitted from the X-ray tube are tapered, and becomes a thin beam after passing through the slit-shaped tungsten collimator.

Tungsten alloy collimator applied for medical CT machine includes tungsten alloy pre-patient collimator and tungsten alloy post-patient collimator. These collimators have the characteristics of high density, smooth surface and good dimensional accuracy.

Tungsten alloy foil is an important anti-scattering component on a CT detector. And there may be 9-129 tungsten alloy anti-scatter foils on a CT detector. Research shows that anti-scattering foils made of high quality tungsten alloy is not easy to deform during long-term use, so the channel width will not change, avoiding signal distortion when X-rays pass through the deformed traditional ray channel, and ensuring imaging quality.

Tungsten alloy radiation shield applied for gamma knife includes a tungsten alloy collimator and its combination block. Their surface is smooth, the size is fine, and the quality is reliable. But why use tungsten alloy radiation shield such as tungsten alloy collimators for gamma knife?
