Stellarray Receives NIH Contract for High Intensity X-ray Sources

23 December 2011

Stellarray, Inc. announced today that it has begun work on a Phase I SBIR contract with the National Cancer Institute of the U.S. National Institutes of Health for the development of High Intensity Digital X-ray Sources (HI-DAXS) for cancer imaging. This project will focus on high intensity cold cathode arrays and innovative architectures for digitally addressable x-ray sources that can be used in stationary computed tomography (CT) systems. Stationary CT is an emerging radiographic imaging system which eliminates the rotating x-ray tube on a mechanical gantry and instead uses multiple x-ray sources to speed up image acquisition. The target application for this new source is digital tomosynthesis for breast cancer screening, a new kind of system which has been shown to increase the accuracy of mammograms.

Mark Eaton, President and CEO of Stellarray, said “HI-DAXS is well-suited to stationary CT and tomosynthesis, as it uses our cold cathode technology to make very fast x-ray pixels in a unique two-dimensional addressing format. This enables CT systems which are faster, more compact and cheaper than anything currently envisioned, with the added benefit of two-dimensional electronic scanning. HI-DAXS may also be an excellent source for phase contrast imaging.”

Dr. Nalin Kumar, Chief Technology Officer, is directing the project. Dr. Kumar has been a leader in cold cathode development for over twenty years and invented flat diamond cold cathodes at the Microelectronics and Computer Technology Corporation, where he and Mr. Eaton were colleagues.

Stellarray develops and produces flat panel radiation sources and systems using them. The company’s first system product is a self-contained blood irradiator (SCBI) for ensuring the safety of transfusion blood supplies without the use of dangerous radioactive isotopes. SCBI uses a simpler version of the company’s flat panel x-ray sources and has been developed with support from the National Heart Lung and Blood Institute of NIH.
