1. A method of imaging a biological sample with a microscopic imaging system, comprising the following steps: (a) imaging the sample to produce a plurality of image-forming signals corresponding to a plurality of pixels on an image of the sample; (b) analyzing said plurality of image-forming signals to produce a measure of image-forming features in said image, wherein said measure is a statistically significant indicator of pathology in portions of said image; and (c) assigning a visually detectable marker to each of said portions of the image corresponding to image-forming signals that produced said measure.
