Question

If a structure having less tissue density than the part of interest is positioned over the AEC detector, which of the following will result?

1) Underexposure
2) Overexposure
3) Distorted image
4) Correct exposure

Answer 1

If a structure with less tissue density than the part of interest is positioned over the AEC detector, it would result in underexposure in an X-ray imaging system.

Step-by-step explanation:

If a structure with less tissue density than the part of interest is positioned over the Automatic Exposure Control (AEC) detector in an X-ray imaging system, the result would be underexposure. The AEC detector measures the amount of X-rays passing through the body and automatically adjusts the exposure settings to achieve optimal image quality. Since the less tissue dense structure allows more X-rays to reach the AEC detector, it would signal the system to reduce the exposure time or adjust other settings, leading to an underexposed image.
