The electric x ray collimator is controlled by remote control. The manual type of occlusion lead leaf opening and closing activity is realized by manually adjusting the knob on the limiter.
The electric x ray collimator type uses an LED lamp to simulate X-rays instead of X-rays to determine the X-ray path through the visible light path, and then through the reflection of the mirror in the x ray collimator, the X-rays are reflected onto the bed surface. Therefore, the light of the LED lamp can pre-determine the size of the illumination field.
The mirrors are typically made of silver-plated plastic with an aluminum equivalent of about 0.5 mm and do not affect X-ray imaging. There is also a clean, transparent plastic plate in front of the x ray collimator with black lines or black dots on the plate to indicate the center of the beam.
The x ray collimator is marked with the size of the illumination field corresponding to the focal length of the knob. The indicator illumination field can be preset in order to adjust the illumination field to lengthen the life of the indicator light after the indicator light is turned on.
