What is the purpose of Automatic Brightness Control in a fluoroscopic exam?

To reduce patient radiation dose
To maintain image brightness by adjusting exposure
To enhance image contrast
To ensure consistent image size

The correct answer is: To maintain image brightness by adjusting exposure

The purpose of Automatic Brightness Control (ABC) in a fluoroscopic exam is to maintain image brightness by adjusting exposure levels. This functionality is essential in fluoroscopy, where real-time imaging is crucial for guiding procedures. ABC helps optimize the quality of the image by automatically adjusting the radiation output based on the characteristics of the patient and the anatomy being visualized. This ensures that the images remain consistently bright and clear throughout the examination, regardless of variations in the patient's body habitus or the specific area being examined. Maintaining optimal image brightness allows healthcare professionals to make accurate diagnoses and perform procedures effectively. Other options, while related to the imaging process, do not accurately define the primary purpose of ABC. For instance, reducing radiation dose is a parallel goal of many imaging techniques and practices, although it isn't the direct function of ABC. Enhancing image contrast and ensuring consistent image size are important in imaging quality but are not the specific objectives that ABC is designed to achieve.
