Where would you typically find a collimator in an x-ray system?

The collimator is an essential component of an x-ray system, serving the primary function of limiting the X-ray beam to a specific area of interest, thereby reducing patient exposure to unnecessary radiation and improving the quality of the image. It is typically found on the underside of the x-ray tube housing. This location allows the collimator to be positioned directly in line with the x-ray tube, ensuring that the newly formed X-ray beam can be accurately shaped and directed towards the imaging receptor while maintaining full control over the beam's dimensions.

The design of the collimator includes adjustable lead shutters that allow for precise changes in beam size and shape, facilitating optimal imaging conditions based on the anatomical area being examined. By placing the collimator on the x-ray tube housing, it is conveniently positioned for efficient operation and immediate adjustment by the radiologic technologist during imaging procedures.
