ZEISS METROTOM 6 scout Industrial Micro-CT System

Overview

The ZEISS METROTOM 6 scout is a high-performance industrial micro-computed tomography (micro-CT) system engineered for non-destructive 3D metrology and internal inspection of large-volume, high-mass components. Operating on the physical principle of X-ray absorption contrast tomography, it reconstructs volumetric density distributions from hundreds of projection images acquired during controlled translation-rotation (TR) motion. Unlike conventional CT systems relying solely on geometric magnification, the METROTOM 6 scout integrates a high-resolution 3k flat-panel detector with optimized X-ray source geometry and precision mechanical kinematics—enabling true micron-level dimensional accuracy across its full 240 mm × 400 mm field of view. Designed and manufactured in Shanghai by ZEISS, this system meets stringent requirements for traceable, repeatable, and auditable measurement in regulated industrial environments—including aerospace, power generation, heavy machinery, and automotive casting validation.

Key Features

• Flat-panel detector architecture delivering high dynamic range and low electronic noise for robust signal-to-noise ratio in dense material imaging.
• Translation-rotation (TR) scanning mode ensuring consistent geometric fidelity and minimizing cone-beam artifacts across large objects.
• Micron-level measurement accuracy validated per ISO 15530-3 and supported by integrated thermal drift compensation and mechanical stability optimization.
• Five-axis kinematic sample positioning system with automated centering—enabling precise alignment of parts within the measurement volume without manual intervention.
• Robust mechanical architecture rated for up to 4800 kg sample load, accommodating oversized castings, turbine housings, and structural assemblies.
• Digital twin integration: real-time synchronization between physical measurement chamber geometry and software-based reconstruction model for enhanced uncertainty quantification.

Sample Compatibility & Compliance

The METROTOM 6 scout accommodates a broad spectrum of industrial materials—including aluminum, steel, titanium, composites, and ceramics—with no inherent restriction on part geometry or wall thickness beyond X-ray penetration limits at operating kV settings. Its 240 mm × 400 mm maximum FOV supports both localized high-resolution scans and full-part volumetric acquisition. The system complies with IEC 61000-6-3 (EMC), IEC 61000-6-4 (industrial immunity), and EN 62471 (photobiological safety). Measurement workflows support GLP/GMP-aligned documentation, including audit trails, user access control, and data integrity features compatible with FDA 21 CFR Part 11 requirements when deployed with ZEISS metrology software suites.

Software & Data Management

Data acquisition, reconstruction, and metrological evaluation are executed via ZEISS INSPECT CT—a dedicated metrology-grade software platform supporting ISO 10360-compliant uncertainty reporting. The software implements iterative reconstruction algorithms (e.g., SART, OS-SART) alongside GPU-accelerated filtered back-projection. All measurement parameters—including beam hardening correction, ring artifact suppression, and voxel calibration—are logged with time-stamped metadata. Export formats include ASTM E2737-compliant CT data packages (.ctset), ISO 10303-21 STEP AP242 for GD&T annotation, and VTK/STL for CAE integration. Data provenance is preserved through hierarchical project versioning and cryptographic hash logging.

Applications

• Dimensional verification of internal geometries inaccessible to tactile CMMs or optical scanners—e.g., cooling channels in turbine blades, core shift in sand-cast engine blocks.
• Pore analysis and defect characterization per ASTM E1559 and ISO 13909 for additive manufacturing and investment casting qualification.
• Assembly verification: detection of missing fasteners, misaligned inserts, or foreign object debris (FOD) inside sealed enclosures.
• Reverse engineering of legacy parts where CAD data is unavailable—enabling direct mesh-to-CAD conversion with GD&T-aware surface fitting.
• Long-term structural health monitoring via time-series CT scans tracking crack propagation or corrosion progression under accelerated aging protocols.

FAQ

What is the maximum sample size the METROTOM 6 scout can accommodate?

The system supports samples up to 240 mm in diameter and 400 mm in height within its field of view; total envelope dimensions depend on gantry clearance and fixture design.
Does the system support automated GD&T evaluation?

Yes—ZEISS INSPECT CT enables fully automated extraction of datums, tolerances, and form deviations per ASME Y14.5 and ISO GPS standards, with statistical process control (SPC) export.
Is the Shanghai-manufactured METROTOM 6 scout certified to international metrology standards?

All units undergo factory calibration per ISO/IEC 17025-accredited procedures; certificate of conformance includes traceability to PTB (Physikalisch-Technische Bundesanstalt) reference standards.
Can the system perform in-situ measurements under thermal or mechanical loading?

While not designed for real-time in-situ loading, the METROTOM 6 scout supports pre- and post-load comparative analysis using identical positioning protocols and reconstruction parameters.
How is measurement uncertainty quantified for regulatory submissions?

Uncertainty budgets follow VDI/VDE 2630 Part 1.1 methodology and are reported in accordance with EURAMET cg-18 guidelines, including contributions from geometry, detector noise, and reconstruction algorithm bias.
