Which image demonstrates an error called saturation?

Saturation refers to a phenomenon where an image loses detail in areas of high contrast because the exposure is too high, leading to areas in the image becoming solid white. This occurs when the intensity of the x-ray beam is so great that it overwhelms the detector, causing these high-exposure areas to be completely white without any discernible detail.

In this context, image D likely displays characteristics of overexposure, where specific areas appear completely white, indicating that the maximum level of brightness has been reached. This results in a loss of information that would normally be critical for diagnostic purposes. Recognizing saturation is essential for radiologic technologists as it directly impacts the quality of the images produced and could lead to misinterpretations if diagnostic details are lost.

Other images (A, B, and C) may not exhibit this complete washout, showing varying levels of exposure or detail retention without experiencing the complete loss of information characteristic of saturation.
