Feasibility of noise-reduction reconstruction technology based on non-local-mean principle in SiPM-PET/CT

Positron emission tomography (PET) using 2-deoxy-2[18F]fluoro-D-glucose (18F-FDG) has been extensively used to diagnose cancer and assess treatment effectiveness [1]. PET diagnosis requires accurate PET image quantification, and standardized uptake value (SUV) is used as a quantification index [2]. However, SUV is generally affected by various factors such as image reconstruction method and point-spread function (PSF) correction [3,4]. SUV has several indices, including SUVmax and SUVmean, of which SUVmax is especially used in clinical practice [5].
