From: Quantification of heterogeneity observed in medical images
Tumors of various size, shape, mean intensity and heterogeneity are shown as assayed via FDG-PET. The letter-number at the top-left indicates the set and ζ-rank within that set. The number at the top-right is the rounded ζ value. The number at the bottom-left is the area of the tumor given in pixels. The sequence of numbers below is the ranks (within the single set) given to the image by the oncologist, the resident and the professional, respectively. The images above were rescaled via nearest-neighbor filtering to a convenient display size; thus, the sizes shown should not be compared directly.
