Journal ArticleDOI
Respiratory gating in positron emission tomography: a quantitative comparison of different gating schemes.
TL;DR: Out of seven different respiratory gating approaches, the variable amplitude method (4) captures the respiratory motion best while keeping a constant noise level among all respiratory phases.
Journal ArticleDOI
List Mode–Driven Cardiac and Respiratory Gating in PET
Florian Büther,Mohammad Dawood,Lars Stegger,Frank Wübbeling,Michael Schäfers,Otmar Schober,Klaus P. Schäfers +6 more
TL;DR: It is demonstrated that valid gating signals during PET scans cannot be obtained only by tracking the external motion or applying an ECG but also by simply analyzing the PET list mode stream on a frame-by-frame basis.
Journal ArticleDOI
Respiratory Motion Correction in 3-D PET Data With Advanced Optical Flow Algorithms
TL;DR: In this article, a combined local and global optical flow algorithm is proposed to correct motion artifacts in positron emission tomography (PET) images for 3D volume sets, which is based on the combined Local and Global Optical Flow algorithm with modifications to allow for discontinuity preservation across organ boundaries.
Journal ArticleDOI
Optimal number of respiratory gates in positron emission tomography: a cardiac patient study.
Mohammad Dawood,Florian Büther,Lars Stegger,Xiaoyi Jiang,Otmar Schober,Michael Schäfers,Klaus P. Schäfers +6 more
TL;DR: The results show that time-based gating underestimates the real respiratory displacement by up to 50%.
Journal ArticleDOI
Detection of respiratory tumour motion using intrinsic list mode-driven gating in positron emission tomography
Florian Büther,I. Ernst,Mohammad Dawood,Peter Kraxner,Michael Schäfers,Otmar Schober,Klaus P. Schäfers +6 more
TL;DR: List mode-driven PET gating, especially the segmented centre of mass method, is feasible and accurate in PET scans of liver and lung tumours.
