Figure 8.20 This photograph illustrates a common set up for image analysis where histology images can
be viewed directly on a computer screen and specific areas can be measured and mapped based on dif-
ferences in staining intensity or other differential markers. This is useful for assessing the size of lesions
or the presence of abnormalities such as excessive iron storage (hemosiderosis) seen in the image on the
computer screen in this photograph. The slide is a liver section from a bird stained with Perls’ iron stain
which indicates the presence of iron stored in tissues.
