When radiation levels are high, what does Automatic Gain Control (AGC) do?

Automatic Gain Control (AGC) is a vital component in imaging systems, especially when dealing with varying levels of radiation. When radiation levels are high, AGC functions to automatically decrease the amplification. This reduction in amplification helps to prevent saturation of the image intensifier, ensuring that the resulting image maintains clarity and detail rather than being overly bright or washed out.

By decreasing the amplification in response to high radiation levels, AGC allows the system to effectively manage the quality of the output image, providing a consistent visual representation. This functionality is crucial in maintaining optimal performance under diverse conditions, allowing for accurate assessment and effective diagnosis.
