There is little difference in structure between automatic X-ray collimator and electric collimator. The difference is that the lead leaf state detection device is set in the automatic X-ray collimator. In terms of function, the automatic X-ray collimator can automatically maintain the size of its irradiated field with the change of the focal screen distance, which is mainly used for fluoroscopy. In fluoroscopy, in order to prevent the patient from receiving unnecessary radiation and prevent excessive X-rays from irradiating the fluorescent screen or image intensifier, the X-ray collimator’s circuit is limited, so when the X-ray collimator of the control rod is in The maximum opening position, the ground radiation field is the same as the diameter of the input screen image intensifier, the size of the radiation field can be tracked and controlled by the change of the focal screen distance, no matter how the focal screen distance changes, the radiation field will not exceed the input screen the edge of.
We at Newheek produce three types of X-ray collimators: electric X-ray collimators, manual X-ray collimators, and automatic X-ray collimators. If you are interested in such equipment, please call the hotline to contact us. !
