April 27, 2015 Torrance, CA

Rapiscan Systems, Inc., a leading global supplier of security inspection systems,today announced that its RTT® 80 (Real Time Tomography) explosives detection system (EDS) has achieved U.S. Transportation Security Laboratory certification for airport checked-baggage screening.

Deepak Chopra, CEO of Rapiscan’s parent company, OSI Systems commented, "We are pleased that RTT 80 has achieved this important regulatory milestone, meeting the rigorous performance standards required by the Department of Homeland Security. We believe RTT can deliver benefits to airports in terms of screening capacity, reliability, security and cost of ownership and we appreciate TSA's approval of this ground-breaking technology."

The RTT employs a proprietary, solid-state approach to provide high-resolution, 3-D imaging. Its unique design allows for high-speed inspection of hold baggage and air cargo, while also meeting recent threat detection standards. RTT has also passed the European Civil Aviation Conference's (ECAC) HBS EDS Standard 3 threat detection requirement and has been deployed by airports globally.

The company expects to submit its Rapiscan RTT® 110 explosives detection system for TSA certification testing in fiscal 2016. The RTT 110 employs the same underlying technology as the RTT 80, but offers a larger tunnel size, capable of screening larger items.
