HAWTHORNE, Calif.--([ BUSINESS WIRE ])--[ OSI Systems, Inc ]. (NASDAQ: OSIS), a vertically-integrated provider of specialized electronics and services, today announced that the Rapiscan RTT (Real Time Tomography) hold baggage screening system has passed the European Civil Aviation Conferenceas (ECAC) Standard 3 threat detection test, the highest standard set by ECAC for the detection of explosive threats in passenger baggage.

"RTTas high resolution enables more accurate threat detection, while the high speed feature of the RTT provides the opportunity to reduce the footprint of screening infrastructure at airports, effectively creating extra room to handle the ever increasing aviation passenger traffic."

RTT is the only Hold Baggage Screening (HBS) system to achieve ECAC Standard 3 performance while also screening bags at up to 1800 bags per hour, which is significantly faster than the CT based HBS systems currently installed at airports. The RTTas unique design allows the processing speed of baggage screening to be at the same rate of speed as airport baggage handling systems, allowing RTT to be installed ain-linea in airportsa existing baggage handling systems without the need to slow down the baggage handling systems.

OSI Systems CEO, Deepak Chopra, commented, aAfter achieving ECAC Standard 3 certification, we look forward to offering the RTT to airports in approximately 43 countries that are ECAC members. RTT, with its unique stationary gantry design, delivers industry-leading throughput, quieter operation, a lighter and smaller footprint, superior reliability, and lower operating and maintenance costs when compared to other HBS products currently available in the marketplace.a Mr. Chopra continued, aRTTas high resolution enables more accurate threat detection, while the high speed feature of the RTT provides the opportunity to reduce the footprint of screening infrastructure at airports, effectively creating extra room to handle the ever increasing aviation passenger traffic.a
