What does automatic rescaling in digital imaging ensure?

Automatic rescaling in digital imaging primarily focuses on ensuring proper brightness. This process adjusts the image data to a standardized range, allowing the final output to maintain visual coherence across different imaging systems and protocols. It compensates for variations in exposure and incident radiation, helping to present an image that appears consistent in brightness regardless of the original exposure levels.

By implementing automatic rescaling, the system can enhance the visibility of structures within the image, making it easier for radiologists and technicians to interpret the images effectively. While other aspects like sharpness, contrast ratios, and color balance are important, they are typically managed through other adjustments and factors outside of the automatic rescaling function.
