Journal Article
A combined PET/CT scanner for clinical oncology.
Thomas Beyer,David W. Townsend,Tony Brun,Paul E. Kinahan,Martin Charron,Raymond Roddy,Jeff Jerin,J. Young,L.G. Byars,Ronald Nutt +9 more
TL;DR: A combined PET and CT scanner is a practical and effective approach to acquiring co-registered anatomical and functional images in a single scanning session.
Journal ArticleDOI
Attenuation correction for a combined 3D PET/CT scanner
TL;DR: The proof of principle of CT-based attenuation correction of 3D positron emission tomography (PET) data is demonstrated by using scans of bone and soft tissue equivalent phantoms and scans of humans to conclude that using CT information is a feasible way to obtain attenuation Correction factors for 3D PET.
Journal ArticleDOI
Exact and approximate rebinning algorithms for 3-D PET data
TL;DR: This paper presents two new rebinning algorithms for the reconstruction of three-dimensional (3-D) positron emission tomography (PET) data that are approximate but allows an efficient implementation based on taking 2-D Fourier transforms of the data.
Journal ArticleDOI
Pain processing during three levels of noxious stimulation produces differential patterns of central activity.
Stuart W. G. Derbyshire,Anthony K. P. Jones,Ferenc E. Gyulai,Stuart Clark,David W. Townsend,Leonard L. Firestone +5 more
TL;DR: Comparisons and correlation analysis indicated a wide range of active regions including bilateral prefrontal, inferior parietal and premotor cortices and thalamic responses, contralateral hippocampus, insula and primary somatosensory cortex and ipsilateral perigenual cingulate cortex and medial frontal cortex.
