Figure 3

Example volumes of interest (VOIs) obtained with various delineation methods for the large primary tumour. Example of axial CT, fused PET/CT and PET images as well as VOIs obtained from CT-based and various PET-based delineation methods (VOIA41, VOIRTL, VOISchaefer, GradWT1 and SUV2.5) for a lung tumour with heterogeneous FDG uptake. Note that the panes of fused PET/CT and PET images are interpolated to match the CT. All other panes use the original image and voxel sizes.
