SANTA CLARA, Calif., FURSTENFELDBRUCK, Germany and YOKOHAMA CITY, Japan,May 13 Samplify Systems, Inc., a real-time compressiontechnology company, Schleifring und Apparatebau GmbH, the market leading slip-ring manufacturer to the medical and defense markets, and Tokyo ElectronDevice Ltd (TED), a leading manufacturer of Xilinx application boards, todayannounced an agreement for the joint development of the world's first slip-ring integrating Samplify's patented Prism CT(TM) signal compressiontechnology for the medical computed tomography (CT) market. Samplify's PrismCT(TM) compression engine is the first compression technology purpose-built toexpand the capacity of CT data acquisition subsystems. By integrating signalcompression technology into the slip-ring Schleifring und Apparatebau will notonly meet the demands of next generation CT machines, but also offer a cost-effective drop-in replacement for existing machines. TED will supplycustomized inrevium(TM) application boards for both data acquisition on therotating gantry, and a PCIe-based data termination card for the hostworkstation.
"Schleifring is the clear leader in the market for slip-rings for the CTand defense markets, and TED demonstrates their ability to deliver customhardware solutions around our technology," said Tom Sparkman, Samplify CEO."We have seen great interest from CT manufacturers in our compressiontechnology, and partnering with Schleifring and TED will accelerate ourability to deliver real hardware-based compression solutions to them."
"Samplify's lossless compression technology is an important tool to helpour slip-ring customers meet their exploding data requirements for future CTor radar platforms, while lowering costs on existing platforms," said KurtDollhofer, Managing Director, Schleifring. "Whether a CT manufacturer wishesto increase slice count, improve detector density, increase rotation rates, oremploy multiple source voltages and focal points, Samplify's compressiontechnology enhances the value proposition of our slip-ring portfolio."
"This is but the first example of the synergy between Samplify'scompression technology and our FPGA and board level design capabilitiesdelivering customized hardware solutions for our customers in the medicalequipment and wireless markets," said Atsushi Tokushige, Corporate Directorand VP of PLD Solutions, TED. "We are pleased to be working with Schleifringas our first inrevium customer in the European market."
Computed tomography systems employ an x-ray source and an array of x-raydetectors, organized into rows and "slices," which rotate around the patientin a helical manner. With each x-ray detector feeding a high resolutionanalog to digital converter channel, high end CT machines require hundreds ofthousands of detectors whose aggregate data requirement exceeds 10 Gbps. Theslip-ring is the communication mechanism between the rotating electronics andthe external workstation. Slip-rings are also employed in defenseapplications for rotating radar antenna arrays and for rotating tank turrets.
Samplify's Prism CT(TM) compression algorithm is available in RTL ornetlist form for leading FPGA families. A single instance of the compressionengine can support sample rates in excess of 200 Msamples/sec, or over 40,000x-ray detectors. Multiple instances can be parallelized to support higherdetector counts. The Prism CT algorithm provides lossless compression of x-ray detector data in a variety of block-floating point formats. It alsoprovides a near-lossless compression mode which achieves higher compressionratios, while preserving signal fidelity within the region of interest.Samplify's Prism CT(TM) decompression algorithm is also available as a dynamiclink library under Windows XP and can support samples rates in excess of 100Msps on a Xeon p
