Figure 1: Overlay of aligned reference (camera) and scanner images to detect dropouts. High-contrast grayscale images from a lossless camera (A, reference) and “wsi” digital scanner whole-slide image (B, Hamamatsu S210, default brightfield settings) were rescaled, aligned, and color coded (C, overlay) so that superimposed overlapping areas are blue, and dropouts are red. Details of three dropout regions include translucent fat (c1, c3) and tissue present on the margins of the slide (c2, “edge”). Case BD2019-2222, tissue from aortic lymph node dissection
