What is the main function of an Automatic Exposure Control (AEC) system in digital radiography?

The main function of an Automatic Exposure Control (AEC) system in digital radiography is to automatically adjust exposure settings to optimize image quality while minimizing radiation dose. AEC systems contribute to achieving consistent and high-quality images by measuring the amount of radiation that reaches the detector and automatically terminating the exposure once an adequate level has been achieved. This not only enhances image quality but also ensures that patients receive the lowest possible radiation dose necessary for effective imaging. By adapting to variations in patient anatomy and thickness, an AEC enhances the overall efficiency of the imaging process while maintaining safety standards for both patients and healthcare providers.

Other options are less relevant because, while speed of imaging may improve as a secondary benefit of optimized exposure settings, it is not the primary function of AEC. Additionally, AEC does not directly create multiple imaging options for the same patient or serve to standardize equipment across different hospitals. Its primary focus remains on image optimization and radiation safety.
