What is the purpose of the ABC (Automatic Brightness Control) in fluoroscopy?

The purpose of Automatic Brightness Control (ABC) in fluoroscopy is to automatically adjust exposure parameters, ensuring that the image remains of consistent quality regardless of variations in patient thickness or composition. This technology optimizes the intensity of the X-ray beam to maintain a specific level of image brightness during the examination, which is crucial for both the quality of the diagnostic images and the safety of the patient. By continuously monitoring the output and making adjustments on-the-fly, ABC helps to minimize radiation exposure while providing clear and detailed images for the radiologist or clinician.

The other options, while related to image quality or patient care, do not directly address the primary function of ABC in managing exposure parameters to enhance image brightness automatically during fluoroscopic procedures.
