Abstract:
In 1991, Ge Wang, the Samuel Reynolds Pritchard Professor of Engineering at Virginia Tech, produced the first paper on spiral cone-beam computed tomography (CT), now an imaging technique used in the mainstream of the medical CT field.

Virginia Tech's proposed next generation nano-computed tomography system will enhance nanoscale research

Blacksburg, VA | Posted on September 8th, 2009


Today, Wang, known as a pioneer in this field, 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 also 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.

"X-ray nano-CT is a cutting edge imaging tool," Wang said, "but a long-standing barrier to realizing its full potential is its inability to precisely reconstruct an interior region of interest within a larger object from purely local projections."

Wang, has a scholarly record of achievements in the imaging world. More than 1000 scientific citations are attributed to his group's pioneering efforts. In 2002, for example, he and his research group pioneered another highly sensitive imaging procedure called bioluminescence tomography (BLT). One application of the in vivo molecular imaging technology became the identification of tumors in live animals.

As an additional example, in 2007 he and his collaborators, Yangbo Ye of the University of Iowa and Hengyong Yu, who is the associate director of Wang's CT lab, patented a novel X-ray imaging method called "interior tomography."

Interior tomography, Wang said, was a first step toward overcoming the long-standing barrier to realizing the full potential of X-ray nano-CT. Despite the ability of this cutting-edge imaging tool as a non-destructive, non-invasive recorder of information, it 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' (SBES) biomedical imaging division 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 www.ictas.vt.edu/index.shtml. The institute has already developed a state-of-the-art nanoscale characterization and fabrication laboratory with capabilities on par with the best nanotechnology labs in the world. With his high-end 500 nanometer micro-CT system, newly funded by the National Institutes of Health (NIH), Wang is making efforts to build an advanced multi-scale CT facility in synergistic combination with the existing university resources as shown in the following chart.

"We are realizing our dream to establish the world's most advanced comprehensive multi-scale and multi-parameter CT facility," Wang said. The use of the facility will be available to other universities and industry.

An academic partnership already exists between Virginia Tech and Xradia www.xradia.com. Xradia is already in talks with Virginia Tech about commercializing the next generation nano-CT system.
