The cross sectional, coronal and sagittal PET images of a male lung cancer patient with different reconstruction algorithms, that the VOI of lung lesions was automatically delineated by 40% threshold of SUVmax, and its quantitative parameters showed significant difference. A The OSEM models, SUVmax = 7.22,SUVmean = 4.51, MTV = 2.96, TLG = 13.35; B The OSEM + TOF models, SUVmax = 7.42, SUVmean = 4.57, MTV = 2.80, TLG = 12.79; C The OSEM + PSF models, SUVmax = 8.88, SUVmean = 5.35, MTV = 2.33, TLG = 12.47; D The OSEM + TOF + PSF models, SUVmax = 9.25, SUVmean = 5.59, MTV = 2.20, TLG = 12.30
