Which process is used to display the digital image with the ideal brightness and contrast?

The process used to display the digital image with the ideal brightness and contrast is achieved through Lookup Table (LUT) adjustments. LUTs are utilized to map input pixel values to output pixel values in a way that enhances the visual representation of the image. By adjusting the LUT, radiologists can optimize the image for better diagnostic interpretation, ensuring that areas of interest are highlighted with appropriate brightness and contrast.

This method allows for precise control over how different intensities in the original image are rendered, enhancing visibility in the regions where diagnostic details are critical. LUT adjustments are particularly effective because they can be tailored to emphasize specific features based on the intended diagnostic outcome, ensuring that the image provides the clearest view of the anatomical structures.

While other processes, such as histogram equalization or contrast stretching, are useful techniques for image enhancement, they do not provide the same level of targeted adjustment that LUT modifications do. Histogram equalization aims to spread out the intensity values across the histogram, which may enhance overall contrast but can lead to loss of detail in specific areas. Contrast stretching also adjusts the dynamic range but less precisely than LUT adjustments. Image filtering focuses on reducing noise or enhancing edges, which may not necessarily improve brightness and contrast directly in the way LUT adjustments do.
