PALS avalanche - A new PAL spectra analysis software

Abstract

A novel concept for tomography of the human body developed by the Jagiellonian Positronium Emission Tomography (J-PET) project provides the possibility to combine metabolic information collected by standard PET with structural information obtained from positronium lifetime. This results in a morphometric image. To this end, there is a need to develop software compatible with the J-PET Framework for fast online analysis during imaging. PALS Avalanche is a software developed on UNIX system and based on ROOT software, which allows one to decompose positronium annihilation lifetime spectra in the form of a set of single time differences and histogram. Performance of the PALS Avalanche will be tested by analysing simulated PAL spectra.
