Object independent scatter sensitivities for PET, applied to scatter estimation through fast Monte Carlo simulation
Simon Noë, Seyed Amir Zaman Pour, Ahmadreza Rezaei +3
Scattered coincidences introduce quantitative bias in positron emission tomography (PET) and must be compensated during reconstruction. Conventional scatter estimates typically rel…

Improved energy-based scatter estimation by incorporating local energy spectra and accelerating the parametric fitting
Seyed Amir Zaman Pour, Ahmadreza Rezaei, Floris Jansen +3
PET requires accurate, precise, and efficient scatter correction techniques. Conventional scatter estimation typically relies on tail-fitted single-scatter simulation (SSS) strateg…
