  Dr. Chang is Professor and Vice-Chairman of Radiology Informatics and Medical Director of Pathology Informatics at the University of Chicago School of Medicine. Dr. Chang is also Medical Director of Enterprise Imaging and the Informatics Architect for the Service Oriented Architecture (SOA) initiative at the University of Chicago Hospitals.

Dr. Chang was the founder and director of the Division of Radiology Informatics at the University of Pittsburgh Medical Center (UPMC). The UPMC digital image management infrastructure supported over 1.3 million clinical studies per year from 19 physically distributed hospitals/facilities throughout Western Pennsylvania. This image management infrastructure also supported cardiac and visible light (ophthalmology, dermatology, and pathology) images as well as numerous large-scale multi-institutional research trials.

Dr. Chang is active in numerous research and development projects related to imaging informatics as well as enterprise-wide informatics integration issues. He is a recognized expert in the field of imaging informatics. His work in workstation design has resulted in presentation and navigation models that have been adopted by most PACS vendors. A novel lossless wavelet-based image distribution mechanism, dynamic transfer syntax (DTS), was co-invented by Dr. Chang; this technology was subsequently commercialized by the creation of Stentor PACS, which was acquired by Philips Medical Systems. This PACS system is used by several hundred hospitals worldwide and currently is second in world-wide market share.

Current informatics initiatives at the University of Chicago under Dr. Chang’s leadership include 1) the development of a robust SOA-based Enterprise Service Bus (ESB) that provides web-services access to clinical information to allow the creation of customized clinical and research applications; 2) an ambitious “closed loop imaging” infrastructure that establishes interoperability across information systems, including modalities, to improve efficiency and quality in image acquisition, interpretation, and results delivery/acknowledgement; and 3) a digital anatomic pathology workflow engine that includes specimen tracking and imaging.

Dr. Chang received his B.A. from Harvard University and his M.D. degree from Stanford University. Concurrent with his medical school training, he also received his M.S. degree in Engineering-Economic Systems from Stanford. Dr. Chang completed his residency and fellowship training in Diagnostic Radiology at Stanford University Hospital.

Dr. Chang has been member of the RSNA Radiology Informatics Committee (RIC) and ACR Informatics Committee. He is a member of the ACR Commission on Clinical Research and Information Technology. He is the informatics consultant to the RSNA for the RadSCOPE electronic education initiative and the myRSNA portal. He has served as course director and/or faculty for over 150 courses for the RSNA and for the Society for Imaging Informatics in Medicine (SIIM) in PACS and radiology informatics. He is a member of the ACR Council Steering Committee. He is a manuscript reviewer for Radiology, American Journal of Roentgenology, Academic Radiology, Journal of Digital Imaging, Radiographics, and is a member of the Journal of the American College of Radiology editorial board. In 2002, he was named as one of the “Top 20 Most Influential People in Radiology” by Diagnostic Imaging. In 2005, he was inducted as a Fellow to the College of the Society for Computer Applications in Radiology (SCAR/SIIM).
