I. Image Quality

Although these terms are rather vague, many physicists work on mathematical models of the imaging process which attempt to combine more specific image attributes (ie, resolution, contrast, and noise) into a single image metric which is appropriate for a specified imaging task (such as detection, classification, activity or size quantitation, etc.) The image metric is typically some sort of signal-to-noise ratio.
