Large scale comparison of maximum likelihood scatter scaling and tail-fitted scatter scaling in LAFOV PET/CT
MLSS provided results of high image quality comparable to the standard method of choice, TFSS, in the clinical routine. The phantom study showed that MLSS provided uptake values accurately relative to the known activity concentration, however less accurate within the cold sphere and insert. MLSS was found to provide robust results across a large patient cohort and is suggested as a suitable substitution for TFSS in the PET image reconstruction process.
