If a digital detector has a larger bit depth, what is the effect?

Explanation:
Larger bit depth lets more brightness levels be displayed in each pixel. Bit depth defines how many discrete gray values a pixel can have, so increasing it expands the number of shades of gray the image can show. This boosts dynamic range and contrast resolution, helping to distinguish similar tissues. For example, 8-bit depth yields 256 levels, while 12-bit depth yields 4096 levels. This change doesn’t alter spatial resolution (which depends on pixel size and sampling) or the number of photons captured, and it isn’t about processing speed. The key effect is the ability to display more brightness levels.
