The past few years have seen significant advances in the development of instrumentation for Positron Emission Tomography (PET). Of particular importance has been the recent appearence of combined PET/CT scanners that can image both anatomy and function in a single device. This presentation will map the milestones in these developments, identifing in particular the role of the physicist in bringing such advances into the clinical arena, and exploring the extent to which they impact patient care.
Biography David W. Townsend Ph.D., joined the University of Tennessee in Knoxville in February 2003 as Professor of Medicine and Radiology, and Director of the Cancer Imaging and Tracer Development Program. He obtained his Ph.D. in Particle Physics from the University of London and worked for eight years at CERN. In 1980, Dr Townsend moved to Geneva University Hospital as a physicist in the Department of Nuclear Medicine. In 1993, he moved to the US as chief physicist in the University of Pittsburgh PET Facility in Pittsburgh. Dr. Townsend is an internationally known researcher and PET physicist who has advanced PET technology for more than 25 years. His group developed the first combined PET/CT scanner, of which over 500 are now in clinical operation worldwide.
