James M. Woolfenden, MD

Professor Emeritus, Medical Imaging

I have over 40 years of experience in clinical nuclear medicine, including service as Chief of Nuclear Medicine at the University of Arizona and Medical Director of Southwest PET/CT Institute.  I have been an investigator on NIH-funded research projects involving instrumentation development and both preclinical and clinical applications of radionuclide imaging since 1976.  Although now retired from clinical activities, I continue to work in the Center for Gamma-Ray Imaging in guiding instrumentation application and assessment in preclinical studies that have translational significance for important biomedical applications. Research Support:  NIH/NIBIB  2P41 EB002035 (H.H. Barrett, PI), 7/01/14-6/30/19: Center for Gamma-Ray Imaging. Goals: this Research Resource will develop advanced gamma-ray detectors and imaging systems, push the limits of spatial and temporal resolution in SPECT and PET, and make state-of-the art technology available to collaborators and the biomedical research community.
