Correction of nonuniform attenuation in cardiac SPECT imaging.
Benjamin M. W. Tsui,Grant T. Gullberg,E. R. Edgerton,J. G. Ballard,J. R. Perry,William H. McCartney,J. Berg +6 more
TL;DR: Results from a heart-lung phantom study and a 201Tl patient study demonstrated that the iterative EM algorithm with attenuation correction provided improved image quality in terms of reduced streak artifacts and noise, and more accurate quantitative information in Terms of improved radioactivity distribution uniformity where uniformity existed, and better anatomic object definition.
Journal Article
Design and Clinical Utility of a Fan Beam Collimator for SPECT Imaging of the Head
Benjamin M. W. Tsui,Grant T. Gullberg,E. R. Edgerton,David R. Gilland,J. R. Perry,William H. McCartney +5 more
TL;DR: Comparative clinical studies on temporomandibular joints (TMJ) between the LEGP and fan beam collimators also confirm the superior image quality obtained with the fanbeam collimator.
Journal Article
The design and clinical utilities of a fan beam collimator for a SPECT system
Benjamin M. W. Tsui,Grant T. Gullberg,E. R. Edgerton,David R. Gilland,T. Rho,R.E. Johnston,J. R. Perry,William H. McCartney +7 more
TL;DR: Clinical comparison of SPECT bone images of the temporomandibular joints obtained with both LEGP and LEFB collimators on the same patients show superior image quality with the LEFB Collimator, which allows improved clearance of the patient's shoulders during rotation.
