List-mode (LM) acquisition allows collection of data attributes at higher levels of precision than is possible with binned (i.e. histogram-mode) data. Hence it is particularly attractive for low-count data in emission tomography. A LM likelihood and convergent EM algorithm for LM reconstruction was presented in (Parra et al., TMI, v17, 1998). Faster ordered subset (OS) reconstruction algorithms for LM 3-D PET were presented in (Reader et al., Phys. Med. Bio., v43, 1998). However, these OS… CONTINUE READING
