Stellarray is bringing to market innovations for irradiation and imaging using the world’s first flat panel radiation sources. Our first products are X-ray panels themselves and a self-contained blood/biological irradiator (SCBI) for ensuring the safety of transfusion blood supplies. Stellarray was spun out of Stellar Micro Devices (SMD) in late 2007 and builds on technology developed by SMD for the Air Force Research Laboratory to safely and rapidly decontaminate biohazards such as anthrax. Panel manufacturing process development was supported by the NIST Advanced Technology Program. The company has received further support from the National Institutes of Health and the Department of Energy, as well as an investment by the Texas Emerging Technology Fund. Stellarray was named one of the “Ten Most Promising Life Science Technology Companies” at the Rice Alliance Life Science Venture Forum in 2009.
All of Stellarray’s radiation panels use cathode arrays, such as our proprietary nano-layered carbon cold cathodes, to provide the innovative shift from point sources, such as X-ray tubes or UV lamps, to panel sources, for major advantages in our target markets. UV radiation panels are made by hitting phosphors with electron beams. The X-ray panels use electron beams from cold cathode arrays fabricated on one side of the panel to strike a metal target (anode) on the opposite side; the X-rays then exit out past the cathodes. If all the cathodes are turned on at once, X-rays emit from the entire panel area, for a plain flat panel X-ray source, or FPXS. In a digitally addressable X-ray source, or DAXS, small groups of cathodes are addressed at specific locations on the panel to make “X-ray pixels”. The X-ray panels can be made in small sizes, e.g. 5” on a side, on up to 20” or more using processes from the flat panel display industry.
