California regulations require the lead collimator to be what size?

In California, regulations specify that the lead collimator must have a size of 2 3/4 inches. This measurement is established to ensure that the collimator adequately limits the x-ray field to the area of interest, thus minimizing patient exposure to radiation and improving image quality. A properly sized and functioning lead collimator is crucial in clinical practices as it helps achieve optimal beam restriction, which plays a significant role in both patient safety and diagnostic efficacy.

Having a collimator that meets the specified size ensures that the equipment adheres to safety standards and effectively contributes to reducing unnecessary radiation scatter. Thus, the requirement of 2 3/4 inches is significant for maintaining the safety and effectiveness of radiographic procedures in medical settings.
