What does ABC stand for in fluoroscopic imaging?

Automatic Brightness Control is a critical feature in fluoroscopic imaging that adjusts the intensity of the x-ray beam automatically based on the subject being imaged. This technology enhances the quality of the images produced during fluoroscopy by maintaining optimal brightness and contrast, ensuring that the anatomical structures are clearly visible while minimizing the radiation dose to the patient and staff.

The system continuously evaluates the image data and makes real-time adjustments to the tube current (mA) and the kilovoltage (kV) settings as needed. By providing consistent image quality while responding to changes in patient size, body composition, or positioning, Automatic Brightness Control allows for more efficient imaging procedures and improved diagnostic outcomes.

In contrast to the other options, which may offer related or alternative technologies, only Automatic Brightness Control accurately describes this widely used mechanism for optimizing fluoroscopic imaging.
