The principle of X-ray collimator

The X-ray collimator is an electromechanical optical device installed in the output window of the X-ray tube.Its main function is to control the irradiation field of the X-ray bulb tube output under the premise of satisfying the X-ray imaging diagnosis, so as to reduce the projection range and avoid unnecessary doses. It can also absorb some scattered light to improve image clarity. In addition, it can also indicate the projection center and the size of the projection field of view. Therefore, the collimator is an indispensable auxiliary device for x-ray irradiation and protection.The manual collimator produced by our company Newheek is mainly used for photography. The opening and closing activities of the collimator covered with lead leaf are realized by manually adjusting the knob or pull rod on the collimator.

In addition to the above, its internal structure is also equipped with a lighting field indicating system. It uses the indicator bulb to simulate the focus of the X-ray tube, uses visible light instead of X-ray, and incident it to the bed surface after being reflected by the mirror. The light path of the reflected visible light is consistent with that of the X-ray passing through the mirror, which can indicate the size of the irradiation field in advance.

Newheek specializes in the production of X-ray machines and radiology equipment, if you need such products, please contact us!
