Next Generation Tomography System
October 5, 2009

Prof. Ge Wang, far right, Virginia Tech director of the Virginia Tech-Wake Forest University School of Biomedical Engineering Sciences' Biomedical Imaging division, works in his nanoscale fabrication characterization research laboratory with Haiou Shen and Fang Liu of the Biomedical Engineering division.

Ge Wang, the Samuel Reynolds Pritchard Professor of Engineering at Virginia Tech, and his colleagues have successfully applied for more than $1.3 million from the National Science Foundation (NSF) to develop the next-generation nano-CT imaging system, which promises to greatly reduce the required dose of radiation.

Virginia Tech and Xradia, a leading nano-CT company, are collaborating on the project with a cost-sharing investment of close to $800,000.

CT is an imaging method that shows objects by sections or sectioning, through the use of x-ray waves and computer processing.

Working with Prof. Wang on this NSF grant are Chris Wyatt, associate professor of Electrical and Computer Engineering; Linbing Wang, associate professor of Civil and Environmental Engineering; and Hengyong Yu, who is the associate director of Prof. Wang’s CT lab, all at Virginia Tech. Also, David Carroll, associate professor of Physics at Wake Forest University, is a member of the team. On the industrial side, the key collaborators are Steve Wang, S. H. Lau and Wenbing Yun.

Together, the team believes they can construct the next generation of nano-CT imaging systems that will provide images that reveal deeply embedded details, including subcellular features. And, they believe they can handle a sample that is ten times larger than what is currently available, and at much reduced radiation dose.
