Reliable Innovation and Rapid Processing for the Entire Airport

Rapiscan Systems Receives $20 Million Order for Advanced Checked Baggage Inspection Systems Based on Real Time Tomography (RTT) Technology

• Initial Order from Manchester Airport Group
• Revolutionary Solid State CT Represents Generational Leap
• Provides Significant Improvement in Baggage Screening Efficiency and Threat Detection

Rapiscan Systems, an OSI Systems, Inc.(NASDAQ:OSIS) company received an approximately $20 million order to provide multiple units of the Real Time Tomography (RTT) Inspection systems to Manchester Airport Group (MAG) in the U.K., where these systems will be used to automatically inspect checked passenger baggage for explosives and other potential threats.  The RTT is a revolutionary solid-state CT system that can achieve speed and operational dynamics significantly superior to existing CT designs.  RTT provides high-resolution 3-D images at exceptional speeds processing up to 1,800 bags per hour, which equates to the highest throughput available on the market today.    Initial models of the RTT are targeted at the aviation checked-baggage inspection market.

Rapiscan Systems’ President, Ajay Mehra, commented, “Our next generation CT system, the RTT, allows airports to upgrade their baggage inspection infrastructure, with minimal modifications, to meet higher standards of screening required in the EU without sacrificing the operational throughput required by airports.  The unique mix of CT detection performance and high throughput positions the RTT in a class by itself, and makes it the first system that truly bridges the gap between EU and US requirements."

The order by Manchester is the initial commercial sale of the Real Time Tomography system, which offers airports significant improvement, over existing security screening technologies, in threat detection and operational efficiency.

OSI Systems' CEO, Deepak Chopra, stated, "We are excited about the first commercial order for the Rapiscan RTT baggage inspection system.   We are especially gratified that Manchester Airports Group, one of the world’s most forward-thinking airport groups, has selected the RTT.  RTT’s design and performance will not only address MAG’s security requirements – it is expected to also provide lower overall operational and services costs than traditional CT based baggage scanners.” 

Andrew Harrison, Managing Director, Manchester Airport, said: “Our order for the RTT technology is the latest innovative development in our approach to aviation security both in terms of improving customer service and managing potential threats.  We have worked closely with Rapiscan on the development of the RTT including its trial at Manchester Airport in 2009.  With its revolutionary design and unprecedented performance, Rapiscan’s RTT will help us to maintain our reputation as one of Europe’s most passenger friendly airports."
