What is the effect of using a faster speed image receptor on patient dose?

Using a faster speed image receptor decreases patient dose because these receptors are more sensitive to radiation. This increased sensitivity allows for higher quality images to be produced with less radiation exposure to the patient. Essentially, a faster speed receptor requires lower exposure settings, which directly correlates with a reduction in the amount of radiation the patient receives during the imaging process.

For example, traditional slower speed receptors often necessitate higher doses of radiation to achieve quality imaging. In contrast, faster receptors can capture the required image more efficiently, making them beneficial not only for patient safety but also for workflow in radiographic procedures.

The other options imply an increase, no change, or variability in patient dose, which does not align with the principles of radiation physics and patient safety practices illustrated in radiographic training. In clinical settings, the goal is always to minimize radiation exposure while still obtaining high-quality diagnostic images.
