When employing collimation in digital imaging, what is the best method to maintain image quality and minimize patient dose?

The best method to maintain image quality and minimize patient dose when employing collimation in digital imaging is to tighten collimation and adjust the borders parallel to the image receptor. This approach ensures that the x-ray beam is only directed toward the area of interest, which improves image quality by reducing scatter radiation that can degrade the image. Additionally, lining the collimation borders parallel to the image receptor maximizes the effective area that is exposed to the radiation, further enhancing image clarity and detail.

By properly adjusting collimation, the amount of unnecessary radiation exposure to the patient is minimized, which is a crucial aspect of radiation safety practices. Tight collimation directs the primary beam precisely where it is needed and eliminates extra exposure to adjacent tissues that are not part of the diagnostic requirement. This practice leads to lower patient doses while still achieving high-quality diagnostic images.

Other options may involve using software or different techniques, but the optimal method that combines effective collimation with proper alignment to the image receptor is the most efficient for achieving both high image quality and low radiation exposure.
