Lyncean Technologies, Inc. has just received a Phase I SBIR grant of $1,296,403 from the National Center for Research Resources (NCRR) to develop "Differential Phase Contrast Imaging" using the unique x-ray beam produced by the Compact Light Source (CLS). The grant will allow Lyncean to continue its ongoing development of the Compact Light Source and its applications to new methods of imaging (http://www.
The Compact Light Source effort was funded by the National Institute of General Medical Sciences (NIGMS) Small Business Innovation Research (SBIR) program as an advanced technology related to the NIGMS Protein Structure Initiative (PSI). The CLS technology is based on an electron beam stored in a miniature storage ring colliding repeatedly with an opposing infrared light pulse stored in a high-finesse cavity. Each collision produces x-rays through inverse Compton scattering. The entire x-ray source fits in a 10x25 ft room similar in size to those used for Magnetic Resonance Imaging in medical clinics.
The first scientific publication using the CLS x-ray beam employed a technique called Differential Phase Contrast Imaging (DPCI) developed by Professor Franz Pfeiffer (now at TU Munich) and collaborators at the Paul Scherrer Institute in Switzerland (http://journals.
This new grant will permit the development of an x-ray imaging system called "The Clinical High Resolution Imaging System (CHRIS)" which takes advantage of the unique properties of the CLS x-ray beam. The CLS x-ray beam emerges from a tiny spot (about 100 microns) and diverges in a cone to illuminate first the sample and then the gratings which are specifically designed to produce x-ray fringes. The diverging monochromatic beam already produces very high resolution images and tomography, due to the point-like source and monochromatic x-ray energy (http://www.
When complete, the CHRIS development aims towards a product which will enable the development of clinical applications of this new imaging method towards cancer detection, mammography, osteoarthritis, small animal imaging and other clinical radiological applications which require the detection of fine structure within soft tissue.
Collaborators on the grant include Prof. Etta Pisano, M.D. from the University of North Carolina and Prof. Franz Pfeiffer, Ph.D. from Technical University, Munich.
Lyncean Technologies, Inc. is located in Palo Alto, California. It was founded in 2001 by Stanford Professor Ronald Ruth, Jeffrey Rifkin, M.A. and Rod Loewen, Ph.D. The Compact Light Source concept is based on research performed earlier by Prof. Ruth, Dr. Zhirong Huang and Dr. Rod Loewen at Stanford Linear Accelerator Center and Stanford University.
