What does ABC stand for in fluoroscopic imaging?

• A. Automatic Brightness Calibration (ABC)
• B. Automated Brightness Control (ABC)
• C. Adaptive Brightness Constant (ABC)
• D. Analytic Brightness Control (ABC)

Answer: (B)

In fluoroscopy, the function being tested is how the system keeps the image brightness steady during dynamic imaging. Automated Brightness Control means the system automatically adjusts the x-ray exposure in real time based on the image brightness, so as the anatomy or patient changes, the brightness stays consistent without manual tweaking. This leads to stable visibility of structures and helps avoid unnecessary radiation by not over- or underexposing frames. Other terms imply different ideas: one-time calibration, a fixed brightness, or a purely analytic method, none of which describe the ongoing automatic adjustment of exposure to maintain constant brightness during live imaging.
