Advisory Board

Gordon Harris, PhD
Director, 3D Imaging Service, Massachusetts General Hospital & Professor of Radiology, Harvard Medical School

Dr. Harris is Director of the 3D Imaging Service, and the former Director of the Radiology Computer Aided Diagnostics Laboratory (RAD CADx LAB) at Massachusetts General Hospital. He is Principal Investigator of the DF/HCC Tumor Imaging Metrics Core (TIMC) at the Dana Farber/Harvard Cancer Center and Professor of Radiology at Harvard Medical School. He received his PhD from Johns Hopkins Medical Institutions in Radiation Health Sciences and a BS in Electrical Engineering from Lafayette College. After graduate school, Dr. Harris spent one post-doctoral year and two years as junior faculty at Johns Hopkins School of Medicine. After four subsequent years as Director of the Neuroimaging Research Laboratory at New England Medical Center, Dr. Harris joined the faculty at MGH and began a new 3D Imaging Service for clinically oriented imaging. His primary research interests include structural and functional brain imaging research in psychiatric and neurologic illnesses including Autism, Alzheimer's disease, Huntington's disease, stroke and Alcoholism. He has developed methods for semi-automated quantitative measurement of tumor volumes for clinical care and clinical trials. Dr. Harris has published and lectured extensively on medical imaging, and currently serves on numerous panels for peer-reviewed journals.
Sandy Napel, PhD
Professor of Radiology, Biomedical Informatics, Electrical Engineering & co-director of the Radiology 3D and the Quantitative Imaging Laboratory, Stanford University

Dr. Napel is a Professor of Radiology and, by courtesy, of Medicine (Biomedical Informatics) and of Electrical Engineering at Stanford University. He is a co-founder and the current co-director of the Stanford Radiology 3D and the Quantitative Imaging Laboratory, and co-section Chief of the Integrative Biomedical Imaging Informatics at Stanford.

Dr. Napel's research interests include developing diagnostic and therapy-planning applications and strategies for the acquisition and visualization of multi-dimensional medical imaging data (e.g., creation of three-dimensional images of blood vessels using CT, visualization of complex flow within blood vessels using MR, and computer-aided detection and characterization of lesions from cross-sectional image data). He also been involved in developing and evaluating techniques for exploring cross-sectional imaging data from an internal perspective, i.e., virtual endoscopy (including colonoscopy, angioscopy, and bronchoscopy), and in the quantitation of structure parameters, e.g., volumes, lengths, medial axes, and curvatures. Finally, Dr. Napel is interested in creating workable solutions to the problem of "data explosion," i.e., how to look at the thousands of images generated per examination using modern CT and MR scanners. He has authored or co-authored over 100 peer-reviewed articles and conference proceedings, and holds over 30 U.S. patents.

Dr. Napel earned his Bachelor of Science in Engineering degree at the State University of New York at Stony Brook, and his MS and PhD degrees from Stanford University.
Geoffrey D. Rubin, MD
George Barth Geller Distinguished Professor of Cardiovascular Research & Professor of Radiology and Bioengineering at Duke University School of Medicine

Dr. Rubin is the George Barth Geller Professor of Cardiovascular Research, Professor of Radiology and Bioengineering, as well as former Chair of the Duke Department of Radiology. Prior to his roles at Duke, Dr. Rubin was professor and section chief of cardiovascular imaging in Stanford University's Department of Radiology. He was also the co-founder and co-director of the Stanford Radiology 3D Medical Imaging Laboratory. Dr. Rubin also held concurrent appointments as associate dean for clinical affairs, associate director of the Stanford Cardiovascular Institute, and vice chief of staff of Stanford Hospital and Clinics.

His current research interests focus on coupling cardiothoracic CT and MRI with novel image processing techniques to detect, characterize, quantify and visualize structures as aids in diagnosis and treatment planning. He has served as the principal investigator of two NIH research project grants (RO1) focused on imaging and analysis of cardiovascular and pulmonary diseases: "Measurement of the Aorta and Its Branches" (1998-2003) and "Improving Radiologist Detection of Lung Nodules with CAD" (2004-present).

Dr. Rubin is the author of more than 135 peer-reviewed manuscripts and more than 50 review articles and book chapters. He has edited five books, including the recently published textbook CT and MR Angiography: Comprehensive Vascular Assessment. He has been listed annually in Americas Top Doctors and Best Doctors in America since 2002 and 2004, respectively. In 2008, he was awarded the Most Effective Radiology Educator award by, a Web site for radiologists and related professionals in the medical imaging industry.

Dr. Rubin received his bachelor's degree with honors from Caltech and medical degree from the University of California, San Diego, School of Medicine. In 1993, he completed his radiology residency and body imaging fellowship training at Stanford. Dr. Rubin has served as the President of the North American Society for Cardiovascular Imaging, President of the Society of Computed Body Tomography & Magnetic Resonance, and President of the Fleischner Society. He currently serves in multiple roles at the American College of Radiology, including Board Member of ACR’s Radiology Leadership Institute and Chair of ACR’s Education Innovation Committee.
Eliot Siegel, MD
Professor and Vice Chairman of information systems at the University of Maryland School of Medicine, Department of Diagnostic Radiology & Chief of Radiology and Nuclear Medicine for the Veterans Affairs Maryland Healthcare System

Dr. Siegel is Professor and Vice Chairman of information systems at the University of Maryland School of Medicine, Department of Diagnostic Radiology and Nuclear Medicine, as well as Chief of Radiology and Nuclear Medicine for the Veterans Affairs Maryland Healthcare System, both in Baltimore, MD. Dr. Siegel is also responsible for the NCI's National Cancer Image Archive and is Workspace Lead of the National Cancer Institute's caBIG In Vivo Imaging Workspace.

Under his guidance, the VA Maryland Healthcare System became the first filmless healthcare enterprise in the United States. He has written over 200 articles and book chapters about PACS (Picture Archiving and Communication Systems) and digital imaging, and has edited six books on the topic, including Filmless Radiology and Security Issues in the Digital Medical Enterprise. He has made more than 1,000 presentations throughout the world on a broad range of topics involving the use of computers in medicine. He has been named as Researcher of the Year, received multiple awards for innovation, including the Smithsonian award, and was selected as runner up Educator of the Year for Diagnostic Radiology. The readers and editorial board of Medical Imaging have selected Dr. Siegel as one of the top ten radiologists for the past two years. He was symposium chairman for the Society of Photo-optical and Industrial Engineers (SPIE) Medical Imaging Meeting for three years, is currently chair of Publications for the Society of Computer Applications in Radiology (SIIM) and has been honored as a fellow in that organization. He is chairman of the RSNA's Medical Imaging Resource Committee, and serves as a Member of the Editorial Board at, Inc. His areas of interest and responsibility at both the local and national levels include digital imaging and PACS, telemedicine, the electronic medical record, and informatics.

Dr. Siegel holds an MD from the University of Maryland.
