Research Topics

Dr. Summers joined the Diagnostic Radiology Department at the NIH Clinical Center in 1994. He is currently Chief of the Clinical Image Processing Service, and directs the Imaging Biomarkers and Computer-Aided Diagnosis (CAD) Laboratory. His research interests include virtual colonoscopy, CAD, multi-organ multi-atlas registration, and development of large radiologic image databases. His clinical areas of specialty are thoracic and gastrointestinal radiology and body cross-sectional imaging. His current research focuses on developing fully-automated interpretation of abdominal CT scans.


Dr. Summers received a BA in physics and the M.D. and Ph.D. degrees in medicine/anatomy and cell biology from the University of Pennsylvania. He completed a medical internship at the Presbyterian-University of Pennsylvania Hospital, Philadelphia, PA, a radiology residency at the University of Michigan, Ann Arbor, MI, and an MRI fellowship at Duke University. In 2000, he received the Presidential Early Career Award for Scientists and Engineers, presented by Dr. Neal Lane, President Clinton's science advisor. In 2012, he received the NIH Director's Award, presented by NIH Director Dr. Francis S. Collins. He is an editorial board member of the journals Radiology and Academic Radiology. He was a co-chair of the Computer-aided Diagnosis program of the annual SPIE Medical Imaging conference in 2010 and 2011. He has co-authored over 300 journal, review and conference proceedings articles, and is a co-inventor on 12 patents.
