Segmentation of tumorous areas in histological sections and their more resembling virtual micro-CT slices. Histological sections of diseased lungs with the tumorous areas delimited by red lines (A,B) and the corresponding virtual micro-CT tomograms shown below (C,D). Red marked areas in the virtual slices correspond to tumors identified using the semi-automated “region grower” tool of VGStudio Max. Tumor burden calculated from the images are shown in Table 1. Scale bar: 1 mm.
