Fast List-Mode Reconstruction for Time-of-Flight PET Using Graphics Hardware

Abstract

Positron emission tomography (PET) measurements with time-of-flight (TOF) information are often very sparse. As a result, direct reconstruction from raw list-mode data is an attractive strategy for dealing with the large dimension spanned by the measurements. However, even though sparse datasets are more efficiently processed in list mode than as sinograms… (More)
