OSI Systems Launches the Rapiscan WaveScan 200 Passive Milimeter-Wave Body Scanner

OSI Systems, Inc. (NASDAQ:OSIS), a vertically-integrated provider of specialized electronic products for critical applications in the security and healthcare industries, announced today at the AVSEC World 2007 conference in Vancouver, Canada, that its Security division, Rapiscan Systems, has launched the Rapiscan WaveScan 200 body scanner. The stand-off passive millimeter wave body scanner can be used either as a standalone solution or integrated with other Rapiscan products to provide a layered security solution in aviation, defense and homeland security environments to efficiently isolate potential threats in real time. Rapiscan Systems President, Ajay Mehra, stated, "We are pleased to launch the Rapiscan WaveScan 200 at the AVSEC World Conference, expanding our range of advanced body scanning technologies. We can offer our customers the choice of screening people for threats either in a stand-off mode utilizing passive millimeter wave technology or in a portal mode utilizing our proprietary backscatter X-Ray technology. Both technologies can also be integrated to form a layered security checkpoint that efficiently detects a wide range of concealed metallic and non-metallic security threats.” About the Rapiscan WaveScan 200 The Rapiscan WaveScan 200 uses advanced passive millimeter wave imaging technology to provide a rapid and discrete method for discerning a wide range of concealed objects such as liquids, gels, explosives, weapons, contraband or other determined security threats. Its technology includes a real-time Radiometric Scanner that images electromagnetic millimeter wave energy, an integrated full-motion video camera, on-board computer and a sophisticated, intelligent video detection engine. A key feature of the passive millimeter wave technology utilized in the Rapiscan WaveScan 200 is that it passively detects electromagnetic energy coming from a subject and therefore can detect concealed objects without transmitting radiation. The Rapiscan WaveScan 200 has the ability to operate remotely from security personnel, a "stand-off” capability that reduces the risk to security personnel and increases operational flexibility.
