Fig. 6

Representative images of isocontour- and gradient-based automatic contouring of PSF images optimised for diagnostic and EARL-compliant purposes. Maximum intensity projections and transverse slices at the level of a necrotic tumour in the right upper lobe of the lung are shown for OSEM, unfiltered PSF images, and PSF images filtered to meet EARL requirements (PSF7). Dice and concordance indices are given for each contouring method, using the MATV extracted from the OSEM images as a reference standard
