Metal artifact reduction strategies for improved attenuation correction in hybrid PET/CT imaging
TL;DR: The origins of metallic artifacts and their impact on clinical PET/CT imaging are discussed, and a brief overview of proposed metal artifact reduction (MAR) methods and their advantages and drawbacks is presented.
Journal ArticleDOI
Development and validation of MCNP4C-based Monte Carlo simulator for fan- and cone-beam x-ray CT.
Mohammad Reza Ay,Habib Zaidi +1 more
TL;DR: The developed simulator is a powerful tool for evaluating the effect of physical, geometrical and other design parameters on scanner performance and image quality in addition to offering a versatile tool for investigating potential artefacts and correction schemes when using CT-based attenuation correction on dual-modality PET/CT units.
Journal ArticleDOI
Generalized whole-body Patlak parametric imaging for enhanced quantification in clinical PET
Nicolas A. Karakatsanis,Yun Zhou,Martin A. Lodge,Michael E. Casey,Richard L. Wahl,Richard L. Wahl,Habib Zaidi,Arman Rahmim +7 more
TL;DR: In this paper, a non-linear generalized Patlak (gPatlak) model is utilized, including a net efflux rate constant kloss, and a hybrid (s/g)PatLak imaging technique is introduced to enhance contrast to noise ratios (CNR) of uptake rate Ki images.
Journal ArticleDOI
Fuzzy clustering-based segmented attenuation correction in whole-body PET imaging.
TL;DR: The technique has been tested on a chest phantom simulating the lungs, heart cavity and the spine, the Rando-Alderson phantom, and whole-body clinical PET studies showing a remarkable improvement in image quality, a clear reduction of noise propagation from transmission into emission data allowing for reduction of transmission scan duration.
Journal ArticleDOI
Comparative evaluation of scatter correction techniques in 3D positron emission tomography
TL;DR: The modified version of Monte Carlo-based scatter correction (MCBSC2) provided a good contrast recovery on the simulated Utah phantom, while the DEW method was found to be clearly superior for the experimental phantom studies in terms of quantitative accuracy at the expense of a significant deterioration in the signal-to-noise ratio.
