The xray collimator is an electromechanical optical device mounted in front of the output window of the x-ray tube assembly sleeve. Its main function is to control the radiation field of the X-ray tube output line to meet the requirements of X-ray imaging and diagnosis. At the bottom, minimize the projection range to avoid unnecessary dose; and can absorb some scattered rays to improve the impact of clarity. In addition, it can indicate the projection center and the size of the projection field. Therefore, the beam beam device is an essential auxiliary equipment for X-ray projection and protection. How should the beam of light be chosen?
Manual xray collimator are mainly used in photography. The opening and closing of the wire shielding guide vanes of the beam limiter can be realized by manually adjusting the knob or the pull rod on the beam limiter. In addition to the above-mentioned internal structure, there is also an irradiation field indicator system.
There are some manual xray collimator and some indicator lights have two levels of brightness to meet the irradiation field indication under the condition of high indoor brightness. The mirror is generally made of silver-plated plastic, and the aluminum equivalent is about 0.5mm, which will not affect the X-ray imaging. In front of the beam limiter there is also a clean transparent plastic plate engraved with black lines or black dots to indicate the center of the ray field. Some beam limiters are marked with the irradiation field size of the corresponding focal length around the knob or within the range of movement of the lever, which is mainly used to preset the irradiation field before the irradiation field indicator light is on, so that after the indicator light is on, it can be quickly Adjust the size of the irradiation field to prolong the service life of the indicator light.
