Unmatched threat resolution in an automated, high-speed explosives detection system

With the best available on-screen threat resolution in its class, the MVT-HR raises the bar for high-speed, high-throughput automated explosives detection. Designed to screen checked baggage of all sizes for explosives and other threats, the revolutionary MVT-HR uses three independent X-ray views to accurately identify suspicious materials and keep false alarm rates low.

Capable of screening 1,800 bags per hour, the rugged and reliable MVT-HR keeps even oversized baggage moving, automatically adjusting to screen skis, golf clubs, or other large items. Advanced multi-view tomography and L-3's landmark image processing software combine in an easy-to-network system designed to meet the toughest explosives detection standards of regulatory agencies worldwide. Completely film safe, the MVT-HR generates crisp images with unsurpassed clarity.

The L-3 Advantage.

Blending maximum detection capability, best-in-class throughput, and pioneering imaging technology, L-3 leads the industry in multi-view tomography explosives detection systems with the MVT-HR, a powerful component of a total passenger terminal security solution.

Unbeatable Image Quality:

Clearer is Better

L-3's proven high-resolution imaging technology and patented, state-of-the-art image processing provide the best on-screen threat resolution and analysis capacity currently available in a multi-view computed tomography explosives detection system.

  • The system's dedicated X-ray imaging subsystem operates at higher currents and sample rates using a fine-pitch detector array to create superior high-resolution images.
  • Thanks to a high signal-to-noise ratio that produces an image with high dynamic range, the MVT-HR's imaging subsystem simultaneously displays materials of different densities.
  • L-3's proprietary Transparent Colorô image processing technique generates crisp images with unsurpassed clarity — without «halo» effects or other distortions.

Innovative Technology:

Advanced Detection for Complex Threats

Designed for flexibility, the MVT-HR delivers peak performance in a variety of settings, whether used as a freestanding unit in a lobby or baggage hall or integrated into a multilevel baggage conveyor system.

  • The system's high-speed analysis keeps false alarm rates to a minimum — in any configuration.
  • Multiple independent X-ray sources, each with a different viewing angle, accurately and rapidly measure mass, density, atomic number (Zeff), and other physical characteristics of concealed items for outstanding automated threat resolution.
  • Multiple detection algorithms can be switched on-the-fly to meet varying explosives detection threat levels.
  • Because it automatically adjusts to screen objects up to 250 cm (98.4") long, the MVT-HR reduces the need for manual searches of out-of-gauge checked baggage, such as golf bags and skis.
  • L-3's proprietary Scatter Detection Enhancement (SDE) technology automatically detects sheet explosives.
  • MVT-HR retains the baseline explosives detection capability of the L-3 MVT that meets the U.S. Transportation Security Administration's criteria for the detection of explosives.

As part of a networked baggage inspection system, the MVT-HR can screen up to 1,800 bags per hour. The system's wide tunnel accepts large or out-of-gauge items and screens objects up to 250 cm (98.4") long

Seamless Networking:

Integration Made Easy

The forerunner in automated, high-speed matrix networking, L-3's full matrix architecture provides a complete multilevel security solution from Level 1X-ray analysis to Level 3 threat resolution. Created with flexibility in mind, the MVT-HR can be integrated into any baggage screening system.

  • L-3 developed the MVT-HR to communicate and operate effortlessly with other L-3 automated equipment in networked installations.
  • With the same overall length, communication links, and interface as L-3's industry-standard VIS-M system, customers operating integrated VIS systems can upgrade to the MVT-HR with little modification to the existing baggage conveyor and control system.
  • Satisfies regulatory and operational requirements for 100% checked-baggage screening at Level 1 operations.
  • Level 2 operators access multiple X-ray views for the most rapid and thorough detection possible.
  • L-3's patented user-friendly touchpad interface maximizes efficiency and minimizes operator fatigue.
  • The system's optional Management Information System (MIS) bridge provides real-time access to critical network data, including Level 1 throughput, alarm rate, fault conditions, and decision times.
