NK-202 Electric X-ray collimator

X-ray collimator (NK-202 electric X-ray collimator), also called beam limiter, is an electromechanical optical device installed in front of the output window of the X-ray tube assembly sleeve. Its main function is to control X-rays. The irradiation field of the output line of the tube can reduce the projection range as much as possible and avoid unnecessary doses under the premise of satisfying X-ray imaging and diagnosis; and can absorb some scattered rays to improve the definition. In addition, it can also indicate the size of the projection center and the projection field of view. Therefore, the beamer is an indispensable auxiliary equipment for X-ray projection and protection.
The NK-202 electric X-ray collimator introduced today is an electric X-ray collimator. The electric beam limiter is mostly used in fluoroscopy, which is convenient for remote control and is an indispensable component for remote control gastrointestinal beds. The opening and closing of the lead leaf of the electric beam limiter is generally driven by a miniature DC motor, and the forward rotation, reverse rotation and running time of the DC motor can be properly controlled, and the irradiation field can be adjusted to the required size. The adjustment of the irradiation field of the electric beam limiter can be carried out on the beam limiter or on the console beside the bed. In addition to continuous adjustment, the latter also has various fixed size irradiation field selection buttons. , As long as you press these buttons, the motor will drive the lead leaf to move to the selected irradiation field and then be fixed to meet the specific requirements of photography. The operation of the motor is provided with limit switches at the closed and maximum open positions of the lead leaf. Automatic limit protection. The electric beam limiter dedicated to fluoroscopy, especially in the fluoroscopy inspection device equipped with an image intensifier, needs to adjust the size of the irradiation field at any time, so there is no need for the irradiation field prediction and light display. Because the input screen of the image intensifier is circular, the structure of the wire-shielding lead leaf generally adopts the leaf type, which can continuously change the diameter of the irradiation field under the operation of the motor.
NK-202 electric X-ray collimator is suitable for tube voltage 150kV, vehicle-mounted, DR digital and ordinary X-ray diagnostic equipment, and the X-ray irradiation field is rectangular. This product complies with the relevant national and industry standards, and has the characteristics of small size, high reliability, and high cost performance.
