MV:3D

The MV:3D is a very-high-throughput inline Explosive Detection System designed for airports where baggage volume exceeds the capacity envelope of rotating-gantry CT scanners. Unlike helical CT architectures that use a single rotating source, the MV:3D employs a stationary X-ray gantry paired with multiple fixed X-ray sources and advanced detector arrays. This architecture eliminates the mechanical rotation cycle time, enabling the system to sustain a continuous belt speed of 0.5 m/s and a rated throughput of up to 1,800 bags per hour — the highest among the Leidos checked-baggage line.

The imaging output is simultaneously a high-resolution 2D projection (1,920 × 1,200 pixels) and a full 3D reconstructed volume, giving automated detection algorithms both density contrast and structural geometry for each bag. The Dieback Tolerant feature allows the conveyor to pause briefly — during a jam clear or upstream sort event — without degrading image quality for the bag currently being scanned, which is critical in high-density inline systems where brief belt interruptions are routine. The large 102 × 81 cm tunnel opening minimises out-of-gauge rejections: with a maximum bag footprint of 250 × 100 × 80 cm and a 290 kg belt load capacity, even the largest checked suitcases, soft bags, and trolley cases pass through without manual diversion.

The MV:3D is certified to EU Standard 3, as demonstrated by the system's selection for Sofia Airport's inline HBS upgrade. The closed-circuit forced-air cooling system removes the need for dedicated air conditioning and supports operation across a 0–40 °C range — relevant for GCC airport plant rooms that face high ambient temperatures. A modular construction approach simplifies transport and installation in below-ground baggage hall plant rooms.
