The Department of Physics is pleased to announce the
2015 Barry Berman Memorial Lecture

Otto Zhou, Ph. D, University of North Carolina at Chapel Hill
The Story of Carbon Nanotube X-Ray
From Scientific Curiosity to Patient Imaging
X-ray radiation is widely used in many aspects of our lives, including medicine, security, and industrial inspection. The way x-ray is generated, however, has not changed significantly since it was discovered over one hundred years ago. Utilizing the unique properties of the carbon nanotubes, we developed a novel spatially- distributed field emission x-ray source array technology. After 10 years of intensive R&D efforts, the technology has been successfully translated from a scientific curiosity to commercial production. Its applications in medical imaging, radiation therapy, and homeland security are being actively investigated, including 3D imaging systems for early detection of breast cancer and lung cancer. Some say technologies are even being evaluated in patient trials. In his talk, Dr. Zhou will describe the working mechanism and properties of the carbon nanotube x-ray source technology and introduce some of its applications in imagining and therapy.
About the Speaker:
Otto Zhou is the David Godschalk Distinguished Professor of Physics and the Lineberger Comprehensive Cancer Center at the University of North Carolina at Chapel Hill. His translational research laboratory develops and clinically validates systems for medical imaging and radiotherapy utilizing the carbon nanotube field emission x-ray array technology pioneered by his team. His current research focuses on digital tomosynthesis for early detection of breast cancer and lung cancer, microbeam radiation therapy for treatment of brain tumor. He has published about 200 technical papers and holds around 50 issued/pending U.S. patents, and is a co-founder of Xintek and XinRay Systems. He received his PhD degree in Materials Sciences from the University of Pennsylvania, trained at the Bell Laboratories and worked at NEC before joining UNC. He is an elected fellow of the American Institute of Medical and Biological Engineering.
About the Lecture Series:
In 2011, The Barry Berman Memorial Lecture Series was created through a generous gift by one of his close collaborators and colleagues, Professor Cedric Yu, a faculty member at the University of Maryland School of Medicine, Department of Radiation Oncology. Professors Berman and Yu formally worked together under a NIH-funded project on radiation cancer therapy. The goal of the lecture series is to inspire young people to study medical physics, by inviting nationally and internationally prominent scientists to speak on the application of physics principles to medicine.
Each gift, no matter how large or small, makes a positive impact on our educational mission and furthers our standing as a dynamic and growing physics department in one of the world’s outstanding universities.
