Read the wording for your board, then hide it and explain Image quality and contrast resolution in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Because the pixel response is linear over a wide range of X-ray intensities, subtle differences in attenuation remain visible, improving contrast resolution.
