Name a common method to ensure that the right amount of radiation is used in imaging.

Automatic Exposure Control (AEC) is a widely used method in imaging that helps to ensure the right amount of radiation is utilized. AEC systems adjust the exposure time based on the density and composition of the area being imaged, allowing for optimal image quality with the minimal necessary radiation dose. This technology continuously monitors the incoming radiation and automatically terminates the exposure once the desired image quality has been achieved.

By using AEC, radiologists can reduce the risk of both underexposure and overexposure. Underexposure can result in poor-quality images that may need repeat imaging, thus increasing the patient's radiation exposure. On the other hand, overexposure can unnecessarily increase the dose the patient receives, which could be avoided with AEC. This method contributes not only to patient safety but also to efficiency in imaging practices, highlighting its importance in minimizing radiation exposure while still obtaining high-quality diagnostic images.
