KA Imaging REVEAL R 35C Portable Tri-Energy Flat-Panel X-ray Detector

Overview

The KA Imaging REVEAL R 35C is a portable, tri-energy flat-panel X-ray detector engineered for high-fidelity spectral digital radiography (SpectralDR®) in field-deployable non-destructive testing (NDT) and security screening applications. Unlike conventional dual-energy systems requiring sequential exposures at two kVp settings — which introduce motion artifacts and temporal misregistration — the REVEAL R 35C employs a proprietary three-layer stacked scintillator architecture to capture low-, medium-, and high-energy X-ray attenuation data simultaneously within a single exposure. This enables intrinsic material decomposition based on photoelectric absorption and Compton scattering cross-section differences across the energy spectrum. The detector operates with standard industrial or security X-ray generators (e.g., Golden Engineering X-ray sources), eliminating the need for specialized hardware or pulsed high-voltage control. Its compact form factor, integrated rechargeable battery, and wireless connectivity support rapid deployment in mobile inspection units, cargo screening checkpoints, aerospace maintenance hangars, and remote infrastructure assessment sites.

Key Features

• Tri-energy spectral acquisition in a single exposure — no motion-induced misregistration between energy channels
• Three-layer scintillator stack with depth-resolved photon energy discrimination (not post-processing interpolation)
• Ruggedized aluminum-magnesium alloy housing rated IP54 for dust and water resistance
• Wireless operation via IEEE 802.11ax (Wi-Fi 6) with end-to-end AES-256 encryption for secure image transmission
• Real-time color-coded material classification overlay: blue (low-Z), green (medium-Z), red (high-Z) — configurable per application threshold
• Built-in radiation dose monitoring with real-time mR/mAs feedback and ALARA-compliant exposure logging
• Onboard FPGA-based preprocessing engine enabling sub-100 ms latency from exposure to display-ready image

Sample Compatibility & Compliance

The REVEAL R 35C is compatible with heterogeneous samples ranging from composite aircraft panels and polymer-wrapped cables to cargo containers and vehicle undercarriages. Its effective detection area (35 cm × 35 cm active area) supports full-field imaging of ISO/IEC 17025-certified reference phantoms used in NDT validation. The system complies with ASTM F792–22 (Standard Test Method for Determining the Performance of X-Ray Systems Used for Screening Checked Baggage and Cargo), including requirements for spatial resolution (≥2 lp/mm at 10% MTF), contrast sensitivity (≥1.5% for 2 mm Al step wedge), and threat detection probability (TDP ≥95% for ICAO-defined threat items). All firmware and acquisition software are designed to meet GLP audit-trail requirements per FDA 21 CFR Part 11, with immutable timestamps, user authentication logs, and electronic signature support.

Software & Data Management

The Reveal™ Acquisition & Analysis Suite v4.2 provides full control of exposure parameters, spectral calibration, and material decomposition algorithms. It supports DICOM 3.0 export with private data elements for spectral metadata (e.g., energy bin assignments, scatter correction coefficients). Raw projection data is stored in HDF5 format with embedded calibration headers, enabling traceable reprocessing using third-party spectral reconstruction tools. The software includes automated QA workflows compliant with EN 13019:2021 for industrial radiography equipment verification. Audit logs record every parameter change, image acquisition event, and user login — all cryptographically signed and exportable as PDF/A-2b for regulatory submission.

Applications

• Aerospace NDT: Detection of impact damage, delamination, and foreign object debris (FOD) in carbon-fiber-reinforced polymer (CFRP) structures
• Cargo & baggage screening: Differentiation of organic explosives, metallic weapons, and shielding materials without false positives from overlapping clutter
• Infrastructure inspection: Corrosion mapping under insulation (CUI), weld integrity assessment in pipelines, and rebar location in reinforced concrete
• Recycling & scrap sorting: Real-time identification of alloy composition (e.g., Ti-6Al-4V vs. stainless steel 316) based on Z-effective signatures
• Field forensics: In-situ analysis of improvised devices with minimal disassembly and radiation exposure

FAQ

Does the REVEAL R 35C require a custom X-ray generator?

No. It is fully compatible with commercially available constant-potential X-ray sources operating between 60–160 kVp, including Golden Engineering models specified in the portable kit.
How is spectral calibration maintained in field conditions?

The detector performs automatic daily warm-up calibration using an internal radioactive reference source (²⁴¹Am), with optional traceable NIST-traceable phantom-based recalibration every 90 days.
Can raw spectral projection data be exported for third-party analysis?

Yes. Unprocessed frame data (three energy-resolved projections per exposure) is accessible in HDF5 format with documented metadata schema, supporting custom decomposition algorithms.
Is the system validated for use in regulated GMP environments?

Yes. Full 21 CFR Part 11 compliance documentation, IQ/OQ/PQ protocols, and validation templates are provided with each unit shipment.
What is the operational temperature range?

–10 °C to +50 °C ambient, with active thermal stabilization maintaining sensor uniformity within ±0.3% gain drift over full range.
