The aim of this study was to investigate the effects of the point-spread function (PSF) and
time-of-flight (TOF) on improving 18F-FDG PET/CT images in relation to reconstruction …

Objective The aim of this study was to evaluate the effect of the point spread function (PSF)
and time of flight (TOF) on PET/CT images of overweight patients in relation to the iteration …

The resolution and quantitative accuracy of PET are highly influenced by the reconstruction
method. Penalized-likelihood estimation algorithms allow for fully convergent iterative …

Purpose: Several investigators have shown that noise equivalent count rate (NECR) is
linearly proportional to the square of image signal‐to‐noise ratio (SNR) when PET images …

The introduction of fast scintillators with good stopping power for 511-keV photons has
renewed interest in time-of-flight (TOF) PET. The ability to measure the difference between …

Abstract Background Recently, a Bayesian penalized likelihood (BPL) reconstruction
algorithm was introduced for a commercial PET/CT with the potential to improve image …

Significant improvements have made it possible to add the technology of time-of-flight (TOF)
to improve PET, particularly for oncology applications. The goals of this work were to …

Abstract Time-of-flight (TOF) and point spread function (PSF) modeling have been shown to
improve PET reconstructions, but the impact on physicians in the clinical setting has not …

Purpose To investigate the clinical performance of a block sequential regularized
expectation maximization (BSREM) penalized likelihood reconstruction algorithm in …

Purpose The objective of this study was to explore the feasibility of harmonising
performance for PET/CT systems equipped with time-of-flight (ToF) and resolution …
