Fig. 5.

A $7.7\text{-}\times \text{-}7.7{\mathrm{mm}}^2$ mosaic consisting of 24 fluorescence image strips of excised tissue from Mohs surgery. Typical features such as sebaceous glands (a) and eccrine glands (b) can be seen. Nests of superficial basal cell carcinomas (c) shown with arrows are observed, showing increased density of nuclei. The mosaic dimensions are $8100\text{-}\times \text{-}8100\mathrm{pixels}$ (width x height) with $8\mathrm{bits}/\mathrm{pixel}$. Note that the magnified areas are display zooms obtained from the original image showing the detail and resolution of the mosaic. The features in the mosaic compare well, in general, to the pathology (Fig. 6) in terms of location, shape, size, nuclei of cells (shown in bright white) and overall morphology of both basal cell carcinomas and normal features.
