Virtual Colonoscopy

A combination of computed tomography (CT) scanning and computer graphics technology, called virtual colonoscopy (VC), is rapidly becoming an alternative to conventional optical colonoscopy. The patient abdomen is imaged by a helical CT scanner during a 40-second single-breath-hold. A 3D model of the colon is then reconstructed from the CT scan by automatically segmenting the colon out of the rest of the abdomen and employing an "electronic cleansing" algorithm for computer-based removal of the residual material. The visualization software, running on a PC, allows the physician to interactively navigate through the colon using volume rendering. An intuitive user interface with customized tools supports "virtual biopsy" to inspect suspicious regions and "painting" to help in visualizing 100% of the colon surface. Unlike optical colonoscopy, VC is patient friendly, fast, non-invasive, more accurate, cost-effective procedure for mass screening of colon polyps.

Short Biography

Arie E. Kaufman is a Leading Professor and Chair of the Computer Science Department, the Director of the Center for Visual Computing (CVC), and Leading Professor of Radiology at the State University of New York at Stony Brook. He was the founding Editor-in-Chief of the IEEE Transaction on Visualization and Computer Graphics (TVCG), 1995-1998. Kaufman has been the co-Chair for multiple Eurographics/Siggraph Graphics Hardware Workshops and Volume Graphics Workshops, the Papers/Program co-Chair for ACM Volume Visualization Symposium and the IEEE Visualization Conferenecs, and the co-founder and member of the steering committee of the IEEE Visualization Conference series. He has previously chaired and is currently a director of the IEEE Computer Society Technical Committee on Visualization and Computer Graphics. He is an IEEE Fellow and the recipient of a 1995 IEEE Outstanding Contribution Award, the 1996 IEEE Computer Society's Golden Core Member, 1998 ACM Service Award, and 1999 IEEE Computer Society's Meritorious Service Award, and 2002 State of New York Entrepreneur Award. Kaufman has conducted research and consulted for over 30 years specializing in volume visualization; graphics architectures, algorithms, and languages; virtual reality; user interfaces; and multimedia. Kaufman has recently co-founded Viatronix Inc. to commercialize virtual colonoscopy, a volume visualization technology for colon cancer screening. He received a BS (1969) in Mathematics and Physics from the Hebrew University of Jerusalem, Israel, an MS (1973) in Computer Science from the Weizmann Institute of Science, Rehovot, Israel, and a PhD (1977) in Computer Science from the Ben-Gurion University, Israel.
