Dose Calculations of SPECT Simulations on Dynamical Targets with GATE / GEANT4
Abstract
Simulations of SPECT studies have been taken attention with
the fact that more accurate results can be constructed in medical imaging with developing
computing techniques. As a result, one can visualize new ideas or improvements
with the help of medical simulations before applying on real incidents for
clinical purposes acquiring high level of statistics without harming live
tissues. In this study, we focused on the capability of GATE (a simulation
toolkit for PET & SPECT) that is developed under GEANT4 simulation
framework and applications on the effects such as activity degradations,
displacements and overlapping of the tissues. Energy histograms and dose
calculations are obtained by using built-in tissues and analyzing virtual data
using ROOT analysis software. Results show the magnitudes of effects that may
have a significant disturbance on SPECT images and their dependence on spesific
parameters.
