Collimator
Circuit/Mechanical Descriptions
The collimator is an electrically actuated mechanism that restricts the x-ray beam to allow the exposure area to only be the size
and shape desired by the operator. The unit has a lead iris and shutters and is mounted directly over the x-ray tube beam
aperture. Software controls the motorized movements to shape the beam after it passes through the fixed primary collimator and
exits the x-ray tube.
The collimator is controlled by software through the Fluoro Functions PCB. The Shutter Width, Rotation and Iris motors set the
size and shape of the x-ray beam under control of the operator. The associated pots confirm the movement and position of the
collimator parts back to the software.
