PETPVC: a toolbox for performing partial volume correction techniques in positron emission tomography
Benjamin A. Thomas,Vesna Cuplov,Alexandre Bousse,Adriana Mendes,Kris Thielemans,Brian Hutton,Brian Hutton,Kjell Erlandsson +7 more
TL;DR: The PETPVC toolbox described in this paper comprises a suite of methods, both classic and more recent approaches, for the purposes of applying PVC to PET data, and the recovery of both GM and a simulated lesion was improved by combining two PVC techniques together.
Journal ArticleDOI
Maximum-Likelihood Joint Image Reconstruction/Motion Estimation in Attenuation-Corrected Respiratory Gated PET/CT Using a Single Attenuation Map
Alexandre Bousse,Ottavia Bertolli,David Atkinson,Simon R. Arridge,Sebastien Ourselin,Brian F. Hutton,Kris Thielemans +6 more
TL;DR: This work provides an insight into positron emission tomography joint image reconstruction/motion estimation (JRM) by maximization of the likelihood, where the probabilistic model accounts for warped attenuation and suggests that a breath-held μ-map can be used.
Journal ArticleDOI
What approach to brain partial volume correction is best for PET/MRI?
Brian Hutton,Benjamin A. Thomas,Kjell Erlandsson,Alexandre Bousse,A Reilhac-Laborde,Daniil Kazantsev,Stefano Pedemonte,Kathleen Vunckx,Simon R. Arridge,Sebastien Ourselin +9 more
TL;DR: Seven novel approaches to partial volume correction were evaluated, including several post-reconstruction methods and several reconstruction methods that incorporate anatomical information, which provided the best recovery with ideal segmentation but were particularly sensitive to mis-registration.
Proceedings ArticleDOI
GPU accelerated rotation-based emission tomography reconstruction
Stefano Pedemonte,Alexandre Bousse,Kjell Erlandsson,Marc Modat,Simon R. Arridge,Brian Hutton,Sebastien Ourselin +6 more
TL;DR: This work proposes an accelerated implementation of a reconstruction algorithm specifically designed to take advantage of the architecture of a General Purpose Graphics Processing Unit (GPGPU) for quantitative reconstruction of radio-tracer activity distribution.
Journal ArticleDOI
Markov random field and Gaussian mixture for segmented MRI-based partial volume correction in PET
Alexandre Bousse,Stefano Pedemonte,Benjamin A. Thomas,Kjell Erlandsson,Sebastien Ourselin,Simon R. Arridge,Brian Hutton +6 more
TL;DR: The proposed segmented magnetic resonance imaging prior-based maximum penalized likelihood deconvolution technique for positron emission tomography (PET) images outperforms the VC algorithm and outperforms SG and RBV corrections when the segmented MRI is inconsistent.
