Anti-Scatter Grids for Security & Baggage Scanners

Product description

Scattered X-rays degrade image quality in security scanning applications, reducing the ability to identify threats and contraband. Nuclear Shields manufactures anti-scatter grids for baggage scanners, cargo inspection systems, and checkpoint screening equipment used in airports, customs facilities, and critical infrastructure protection.

Clearer images for threat detection

Security operators rely on image quality to identify weapons, explosives, and prohibited items. Scatter adds noise and reduces contrast, making it harder to distinguish objects within cluttered baggage. Our anti-scatter grids reject scattered radiation before it reaches the detector, improving the signal-to-noise ratio and delivering sharper images for faster, more confident screening decisions.

1D and 2D grid configurations

We offer both one-dimensional and two-dimensional grid designs depending on your scanner geometry and scatter rejection requirements.

1D grids feature linear septa that reject scatter in the primary direction. These grids suit conventional line-scan baggage systems where scatter predominantly originates from within the scan plane.

2D grids add perpendicular septa to create a cellular structure that rejects scatter from all directions. This configuration delivers superior performance for CT baggage scanners and systems with wide X-ray beams where scatter arrives from multiple angles.

Tungsten and lead options

Grid septa are available in tungsten or lead. Tungsten provides higher attenuation per unit thickness, enabling thinner septa for fine-pitch detectors. Lead offers a cost-effective solution where septa thickness is less constrained. We recommend the appropriate material based on your detector resolution and energy spectrum.

Engineered for your detector

Security scanner manufacturers use various detector technologies and geometries. We engineer grids specifically for your system, matching septa pitch to detector pixel dimensions and aligning the grid focal geometry to your source position. Whether you need grids for a new scanner design or replacement grids for existing equipment, we deliver components that integrate correctly.

High-throughput environments

Airport checkpoints and cargo facilities process large volumes continuously. Our grids are built for durability in demanding operational environments. Consistent manufacturing quality ensures reliable performance across production volumes for OEM scanner programs.

Applications

Airport baggage screening

Anti-scatter grids for checkpoint baggage scanners and checked luggage CT systems. Improve detection capability while maintaining the throughput rates that airport operations require.

Cargo and freight inspection

Grids for large-format scanners used to screen shipping containers, pallets, and air cargo. These systems often operate at higher energies where scatter fractions are significant.

Customs and border security

Scanner grids for vehicle inspection systems, mail screening, and parcel inspection at border crossings and customs facilities.

Critical infrastructure protection

Grids for security scanners deployed at government buildings, event venues, and other facilities requiring access control screening.
