Lawrence MacDonald, Ph.D.

Research Associate Professor

Biography

Dr. Lawrence MacDonald received a B.S., in Physics from the University of Minnesota and a Ph.D. in Physics from the University of California, Los Angeles. He is currently a Research Assistant Professor in the Department of Radiology at the University of Washington. Dr. MacDonald’s research has focused on high-resolution dedicated nuclear imaging systems that included a pre-clinical SPECT-CT system and a small gamma camera for breast imaging and intra-operative sentinel lymph node imaging. His current work includes evaluation of clinical and physics performance of a positron emission mammography system and developing a fully tomographic high-resolution PET scanner that mounts to a conventional mammography gantry. This system will be optimized for PET-as-biomarker applications such as selection and monitoring breast cancer treatments, and clinical trials of new therapies.
