A radiographic histogram is a graphic representation of which concept?

Explanation:
A radiographic histogram shows how often each gray value occurs in the image, which corresponds to the distribution of detector exposure across the scene. The horizontal axis maps pixel gray levels (exposure), while the vertical axis shows how many pixels have each value. This makes it a graphic representation of the frequency of specific exposure values captured in the image. It helps assess and adjust exposure and image processing, but it does not directly describe spatial resolution, SNR, or patient dose estimates.
