The collimator (collimator NK202) is mainly connected with the tube, and its function is to position and use when setting up, and simulate the radiation area of the X-ray machine, which can reduce the measurement of patient radiation and enhance the image quality. In addition, it can also indicate the projection center and the size of the projection field of view. Therefore, the beam beam is an indispensable auxiliary device of the X-ray machine.
The manual collimator (collimator NK202) is mainly used for filming. The opening and closing activities of the collimator covering the lead leaf can be realized by manually adjusting the knob or pull rod on the beam limiter. In addition to the above, its internal structure is also equipped with a lighting field indicator system.
The manual collimator NK202 is mainly used for fixed X-ray machines, mainly matched with 150 KV X-ray tubes.
