An x-ray exposure above the highest level of the exposure latitude may result in an image error called:

An x-ray exposure that exceeds the highest level of exposure latitude leads to saturation artifact. This phenomenon occurs when the digital detector is overwhelmed by excessive radiation, resulting in a loss of image detail and information in the areas that received the highest doses of radiation. Specifically, these areas may appear completely white or lacking in texture, as the sensor cannot record any additional data beyond its saturation point.

In digital radiography, maintaining exposure within the specified latitude is crucial for achieving optimal image quality. When exposure is too high, it compromises the ability of the system to produce a diagnostic image, effectively "clipping" the data and erasing critical information that could assist in the diagnosis.

This understanding emphasizes the importance of correctly adjusting exposure settings to ensure the captured images are both diagnostically adequate and within the operational limits of the imaging technology used.
