Nk-202 electric collimator
Electric Collimator is also known as X-ray collimator, is an electromechanical optical device installed in the output window of the X ray tube assembly. Its main function is to control the radiation field of the X ray tube output line, so as to minimize the projection range and avoid unnecessary dose on the premise of meeting the requirements of X ray imaging and diagnosis.And can absorb some scattered rays, improve the clarity of the impact.In addition, it indicates the projection center and the size of the projected field of vision.Therefore, the beam is an indispensable auxiliary equipment for X-ray projection and protection.
The NK-202 beam limiter introduced today is an electric beam limiter, which is mostly used in fluoroscopy for remote control and is an essential component for remote control gastro-intestinal bed.The opening and closing of the lead blade of the electric beam limiter is generally driven by the micro-DC motor, and the irradiation field can be adjusted to the required size by properly controlling the forward, reverse and running time of the DC motor.Electric limited beam radiation fields both in the limit of the regulation of beam splitter, also has in the bedside table to control the operation, the latter except for continuous adjustment, there are a variety of fixed size the radiation field of option buttons, just press the button, the motor is driven lead leaf movements to the selected fixed after radiation field, in order to meet the specific requirements of photography.The motor is operated with a limit switch at the lead blade closing and maximum opening position.Automatic limit protection.The electric beam limiter specially used for perspective, especially in the fluoroscopy device equipped with image intensifiers, does not need the field indication and light display because it needs to adjust the size of the field at any time.As the input screen of the image intensifier is circular, the structure of the lead leaf is generally adopted in the form of leaf flap, which makes the diameter of the irradiation field continuously change under the operation of the motor.
The NK-202 electric medical X-ray beam limiter is suitable for 150kV tube voltage, vehicle-mounted, DR digital and ordinary X-ray diagnostic equipment. The X-ray field is rectangular.This product conforms to the relevant national and industrial standards, with small size, high reliability, high cost performance characteristics.
