Fig. 7From: Use of non-Gaussian time-of-flight kernels for image reconstruction of Monte Carlo simulated data of ultra-fast PET scannersPeak-to-valley ratios of all combinations of crystals with an idealised scanner as function of the iteration number. The six rod section had diameters of (A) 7.0 mm, (B) 5.0 mm, (C) 4.0 mm, (D) 3.5 mm, (E) 3.0 mm and (F) 2.5 mm, for the CTR (fD), Gaussian with data boundaries (fN) and without data boundaries (\(f^{\prime }_{N}\)) kernelsBack to article page
