What does insufficient exposure in a digital image primarily affect?

Insufficient exposure in a digital image primarily affects the resolution and clarity of the anatomical details. When an image is underexposed, the overall density is too low, causing important anatomical features to be obscured or not visualized properly. This can lead to a lack of diagnostic quality because subtle details that are crucial for accurate interpretation may be lost or difficult to discern.

Digital radiography relies on proper exposure levels to ensure that the detector captures enough data to represent the anatomy accurately. When exposure is adequate, the image appears with proper contrast and brightness, allowing for enhanced visibility of structures. Therefore, achieving the right exposure is essential for ensuring that all relevant anatomical details are clearly displayed in the final image, which is vital for accurate diagnoses and treatment planning.
