So What? Who Cares?2
Checkpoint baggage screening has limited ATR and has difficultly with overlapping items, electronics, and liquids due to limited x-ray views.
Checkpoint baggage screening currently requires passengers to divest liquids and electronics which increases the number of scanned items and frustrates passengers.
ATR at the checkpoint will increase detection, improve passenger experience, and reduce load on operators.
ATR requires CT like images. Current CT systems do not easily fit into the current checkpoint.
Fixed gantry CT systems could be a better fit into the checkpoint, provide faster imaging, and operate more reliably.
NuRay’s multi-beam X-ray source provides a solution for Checkpoint CT: Combines CNT multibeam tubes with fixed gantry CT geometry.
Has a simple and modular design.
