The purpose of this paper is to propose a friendly computational framework able to investigate particles tracking through different compartments of the human being using dedicated numerical *** main building blocks of this framework are:(i) convenient X-ray spectra calculator for different filter/anode combination,(ii) realistic voxelized computational human phantom,(iii)validated Geant4-based Monte Carlo simulation,and(iv)extendable and free image processing *** studied the multimodality SPECT/CT cardiac imaging using specific spectrum of the ^(99m)Tc and 120 kVp X-ray beam,for internal and external exposure,*** application of the framework to quantify the loss of information between combined and simultaneous coregistration was carried *** main objectives were addressed:(i) an ideal geometry was simulated for educational purposes(ii) a realistic case study was carried out,for research purposes,concerning the modeling of the GE Infinia II 3/800 Gamma *** compared the effect of using a Na I(Tl) and CZT crystal detector,and a LEHR and MEGP collimator with different uptake values of the heart organ(1:1,5:1 and 50:1) for both simultaneous andcombined SPECT/CT *** confirmed the usefulness of the Na I(Tl) crystal with the LEHR collimator for such kind of study.
