▲ [25a-D113-10] Direct SSS Application through Accurate System Model
キーワード：PET, Scatter Correction
In PET image reconstruction, scatter correction is conducted for more quantitatively correct imaging. One of scatter correction methods is Single Scatter Simulation (SSS) method. This method has benefit of case specific scatter correction so that it can be suitable for asymmetric source distribution which can be problematic with other methods for scatter correction. Usually, this method is to calculate scatter contribution estimation through simulation then fits and scales to experimental sinograms for practical scatter fraction calculation.
In this study, accurate modelling of system matrix and SSS are conducted to estimate scatter fraction on each channel directly case-specifically. Details will be discussed in the presentation.Geant4 simulation was conducted to evaluate the suggested method.
