SECURITY

The usage of new multiple energy X-ray technology, coupled with advanced three-dimensional imaging:

  • Eliminates the current need for operator based re-inspection, corresponding to 30%;
  • Reduces footprint and weight by a factor of >2, compared to CT
  • Increases inspection conveyor line speed to 40 meter/minute (maximum 2,400 bags/hour, a 33% increase)
  • Decreases system pricing and running costs by up to 50%.

The technical advantage is a substantially simpler design, mechanically and electrically, compared to CT scanning. This leads additionally to reduced maintenance costs and longer life in service.

MAIN FEATURES

  • Optional conveyor width to 2000 mm
  • Multiple lane solutions
  • Production speed to 200 m/min
  • Detection down to 0.2 mm
  • Ultra high sensitivity
  • Sorting into different quality categories

APPLICATION AREAS

The growing security challenge is reinforced by the rising number of flight passengers. It often creates chaos and delays in the airports’ baggage handling systems. But now, a solution to this problem may be on its way. A range of companies and research groups in the Danish X-ray industry have partnered up to develop more efficient screening systems for the security check of luggage in airports.

The innovative solution is to use multiple energy (spectral) data acquisition in a very specific manner, so that an image is created which includes information on the specific materials represented in the inspected luggage, with automatic identification of threat items.

The solution is developed through two separate R&D projects, focusing on the creation of a scanner for checked in luggage, and a novel security scanner. Read more on the project pages.

The innovative solution of a novel real-time X-ray inspection concept is to use multiple energy (spectral) data acquisition in a very specific manner, so that an image is created which includes information on the specific materials represented in the inspected luggage, with automatic identification of threat items.

This technology is cost-effective for general security tasks, e.g for applications relative to big audiences, exhibitions, cruises, hotels, etc. The big advantage is the ability to provide the assessment of threats posed by liquids, gels, and chemical compounds, in addition to the general X-ray image of the (bag) contents.

The concept uses multi-energy imaging detectors in combination with intelligent pre-screening, a priori information, and large databases which allows the fitting of the actual X-ray attenuation “profile” to a matching set of material combinations. The approach is specifically relevant for general security applications where the time of the inspection is a critical parameter.  The inspection is based on an automatic recognition of threat compounds and therefore will speed up the human decision taking meaning less time per scanned “person”. In addition, the ability to determine a threat substance with a high probability gives much more value.

Specifications

The system has an integrated climate control system and can be used even in very warm climates. It integrates a long conveyor section, and the system is very rigid, built for remote deployment. Short startup time and easy closedown procedure add to the benefits.

The key benefit is the ability to identify threat liquids based on one single projection. The system is available for general security screening, based on human image interpretation, aided by the system threat identification. The system will inspect general bags up to 40 x 40 cm in cross-section and will provide an alarm to the operator if for any reason the inspection of the bag is problematic (due to content, threats, or otherwise). Inspection speed is 20 m/min. Typical throughput up to 0.5 people (bag) per second.

CASE STORY

We are still working on a case story for this application, which will be ready shortly. In the meantime, feel free to flick through our case story on fish bone detection.
