    • + The analytic Spline Reconstruction Technique (SRT) algorithm has been added in 2 different versions: for PET + (inverting the 2D Radon transform) and for SPECT (inverting the 2D attenuated Radon transform). The latter + allows quantitatively correct analytic reconstruction of SPECT data (after scatter correction). + + The reference for the implemented algorithms is:
