Perceived image quality. Each pathologist rated each whole slide image as "Excellent" ("Flawless – superb color and sharpness/focus"), "Diagnostic" ("Minimal distortion – quality is high enough to render a diagnosis") or "Poor" ("Extreme distortion – quality makes diagnosis difficult or impossible"). No whole slide image was rated "poor" by more than one pathologist. Six of seven times, the reason for a "poor" rating was that "key areas were out of focus".
