Virginia Tech's proposed next generation nano-CT system will enhance nano-scale research
Date:9/3/2009

cannot "precisely reconstruct an interior region of interest within a large object from purely local projections," Wang said. And, when used in medicine, a patient is subjected to "a radiation dose that must be increased dramatically to obtain improved resolutions."

Wang suggested to the NSF that the combination of X-ray nano-CT and interior tomography will provide "a versatile nano-imaging tool that can visualize fine features within a larger object, and use a much lower radiation dose and in much less time." This new work is the foundation of the NSF project.

Working with 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 Yu, 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, they believe they can construct this next generation of a nano-CT imaging system that will provide images that will reveal deeply imbedded 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," Wang explained.

Wang, director of the Virginia Tech-Wake Forest University School of Biomedical Engineering Sciences' biomedical imaging division, http://www.imaging.sbes.vt.edu is also the founding editor-in-chief of the International Journal of Biomedical Imaging. He is the associate editor of the Institute of Electrical and Electronic Engineers (IEEE) Transactions on Medical Imaging and others.

SBES is part of the University's Institute for Critical Technology and Applied Science (ICTAS). http://www.ictas.vt.edu/index
