The threat posed by dangerous consignments continues to present significant challenges for public authorities and operators of critical infrastructure. In addition to letter and parcel bombs, modern security concepts are increasingly focusing on hazardous chemicals, narcotics and prohibited items. To effectively counter these risks, organisations are increasingly relying on high-performance X-ray systems that enable the rapid and reliable assessment of suspicious consignments.

Against this backdrop, a Lithuanian government agency has opted for the AXIS CXi post office X-ray system from the British manufacturer 3DX-RAY. With this contract, the company is further expanding its presence in the European security market and underscores the growing demand for modern screening solutions for public authorities and facilities with heightened security requirements.

Material detection through colour differentiation

The AXIS CXi adapts technology previously known primarily from airport baggage screening for use in post offices. At the heart of this is colour-based material differentiation, which enables a significantly more comprehensive analysis than traditional greyscale X-ray images.

Whilst organic materials – including explosives, narcotics, chemicals and foodstuffs – are displayed in orange, metals such as firearms, knives or components of improvised explosive devices appear in blue. Inorganic materials, which frequently occur in connection with homemade explosive devices, are highlighted in green. A greyscale mode is also available, which is particularly useful for the precise detection of shapes and contours.

This multi-level visualisation enables security staff to assess potentially dangerous contents more quickly and immediately distinguish between different types of material. This is intended, particularly in postal facilities, to help identify suspicious items more efficiently whilst reducing the training requirements for operating staff.

Performance assessed according to recognised test procedures

To assess image quality, the AXIS CXi was evaluated using the British Mail Screening Test Piece (MSTP). This recognised test procedure is used to evaluate X-ray systems for postal screening and examines, amongst other things, resolution, penetration capability and the ability to reliably visualise complex combinations of materials within letters and parcels.

The results of tests 1 to 8 provide users with an objective basis for assessing system performance and support the selection of suitable screening technologies as part of a holistic security concept. The test methodology is based on the principles of the British standard PAS 97:2021, which sets out the requirements for security measures in postal facilities.

Large inspection chamber with a compact design

In addition to imaging, 3DX-RAY particularly highlights the system’s design. The AXIS CXi combines a comparatively large inspection chamber with a compact footprint, thereby expanding the traditional scope of application for post office X-ray systems.

In addition to letters and parcels, bags and hand luggage can also be screened. Thanks to its mobile design, the system can be deployed flexibly at various locations. According to the manufacturer, the X-ray system’s understated design makes it equally suitable for government agencies, corporate headquarters, hotels, financial institutions and retail outlets.

Growing demand for modern postal security

According to Vince Deery, CEO of 3DX-RAY, the AXIS CXi was developed to make the colour X-ray technology familiar from aviation security screening available for use in postal facilities. Since its market launch, the system has proven itself in various security applications and has continuously expanded its range of possible uses.

The new order from Lithuania underscores the international expansion of the installed systems. Government institutions, in particular, are exposed to a growing range of potential threats that could be smuggled in via letter and parcel services. Modern screening technologies must therefore enable security officials to examine suspicious consignments quickly, reliably and with a high degree of assessment certainty.

With this latest project, 3DX-RAY is strengthening its position in the European security market. At the same time, the award of this contract highlights the trend towards user-friendly and high-performance X-ray systems designed to meet the increasing demands for the protection of public authorities, critical infrastructure and other security-sensitive facilities.
