Tungsten Alloy Pre-patient Collimator Applied for CT Machine

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 pre-patient collimator applied for CT machine image

In recent months, CT machines such as CT scanners have been mentioned and used more frequently due to the prevalence of novel coronavirus pneumonia. CT uses accurate collimated X-ray beams to achieve cross-sectional scanning, and X-rays are radiant. In order not to expose the patients to excessive radiation, all CT machines and CT rooms are specially designed. For example, tungsten alloy pre-patient collimator, in addition to obtain clear imaging, it has good radiation shielding effect, as tungsten alloy is a new type of environmental protection radiation protection material with stronger radiation absorption ability than traditional lead.
