Always Imaging AX-3000CT-M Metrological Microfocus Industrial CT System

Overview

The Always Imaging AX-3000CT-M is a metrological-grade microfocus industrial computed tomography (CT) system engineered for non-destructive, high-fidelity 3D volumetric imaging and quantitative dimensional metrology. Based on cone-beam geometry and filtered back-projection reconstruction algorithms, the system employs a high-stability open-tube microfocus X-ray source—available in reflective or transmissive target configurations—with selectable focal spot sizes down to 1.5 µm (optionally 800 nm at 180 kV). Coupled with a large-area, high-dynamic-range digital flat-panel detector (3072 × 3072 pixels, 139 µm pixel pitch), the AX-3000CT-M delivers sub-micron spatial resolution in optimized acquisition protocols and density contrast sensitivity better than 1%—enabling precise internal defect detection, porosity quantification, wall thickness analysis, and GD&T-compliant geometric dimensioning and tolerancing (GD&T) evaluation per ASME Y14.5 and ISO 1101.

Key Features

• Metrological validation framework: Integrated traceable calibration artifacts and software-based uncertainty estimation aligned with VDI/VDE 2630 Part 1.3 and ISO/IEC 17025 requirements for measurement system verification.
• Modular radiation shielding: Fully enclosed lead-lined cabinet certified to GBZ 130-2020 (China) and compliant with IEC 61331-1 for occupational dose limits (<1 µSv/h at 5 cm from enclosure surface).
• Multi-energy X-ray source platform: Three configurable high-voltage options (225 kV, 240 kV, 300 kV) support broad material penetration—from low-Z polymers and biological tissues to high-density alloys and geological cores—without hardware modification.
• Rotation-only (RO) scanning architecture: Precision air-bearing rotational stage with angular repeatability <0.001° and radial runout <1 µm ensures mechanical stability critical for metrological repeatability.
• Configurable sample handling: Three payload tiers (25 kg, 50 kg, 100 kg) accommodate diverse specimen geometries up to Ø600 mm × H800 mm; optional motorized tilt/translation stages enable multi-axis alignment for complex part positioning.
• Cooling and thermal management: Closed-loop chiller system maintains source and detector thermal drift within ±0.1°C over extended scan durations (>8 hours), preserving long-term measurement consistency.

Sample Compatibility & Compliance

The AX-3000CT-M supports non-destructive inspection of heterogeneous, multi-material specimens including injection-molded polymer components, semiconductor packages, fossilized paleontological specimens, electronic assemblies (PCBs, BGA solder joints), rock cores (sandstone, shale, carbonate), composite laminates (CFRP, GFRP), soil aggregates, and soft-tissue phantoms. All system configurations comply with national radiation safety regulations (GBZ 130-2020), electromagnetic compatibility standards (GB/T 18268.1), and mechanical safety directives (GB/T 23286.1). For regulated industries—including aerospace (AS9100), medical device manufacturing (ISO 13485), and pharmaceutical packaging (USP ), the system supports audit-ready documentation packages and can be configured with 21 CFR Part 11–compliant user access control and electronic signature modules.

Software & Data Management

Controlled via Always Imaging’s proprietary CT-Studio v5.x platform, the AX-3000CT-M provides integrated workflow management from acquisition planning (dose optimization, projection count selection, ROI masking) through reconstruction (FDK, iterative SART, GPU-accelerated FBP), segmentation (adaptive thresholding, region-growing, deep learning–assisted phase separation), and metrological analysis (ISO 5725-based uncertainty propagation, CT-specific GD&T evaluation per VDI/VDE 2630). Raw projection data is stored in DICOM-CT and HDF5 formats; processed volumes are exportable as STL, PLY, or voxel-based NRRD files. Audit trails, calibration logs, and user action histories are retained for ≥10 years and support GLP/GMP-aligned quality review processes.

Applications

• Aerospace & Defense: Wall thickness mapping of turbine blades, porosity analysis in investment-cast superalloys, fiber orientation quantification in ceramic matrix composites.
• Electronics: Void detection in solder joints, wire bond integrity assessment, encapsulant delamination measurement in advanced packaging.
• Geosciences: Pore network modeling in reservoir rock cores, mineral phase distribution in ore samples, microfracture characterization in shale.
• Advanced Manufacturing: First-article inspection of additively manufactured metal parts, shrinkage and warpage validation in injection molding tooling, internal channel verification in conformal cooling inserts.
• Life Sciences & Materials Research: 3D morphometric analysis of bone scaffolds, vascular network reconstruction in ex vivo tissue specimens, filler dispersion homogeneity in nanocomposites.

FAQ

What metrological standards does the AX-3000CT-M support for dimensional validation?
The system conforms to VDI/VDE 2630 Part 1.3 for CT-based coordinate measuring machines and supports traceable calibration using certified reference objects (e.g., sphere plates, step gauges) with documented uncertainty budgets.
Can the system perform density quantification for material composition analysis?
Yes—via calibrated linear attenuation coefficient mapping, the AX-3000CT-M enables relative density comparison across regions-of-interest with resolution better than 1%, suitable for void fraction, inclusion grading, and phase segregation studies.
Is dual-energy CT capability available?
Not natively integrated; however, sequential acquisitions at two distinct kV settings (e.g., 225 kV and 300 kV) can be performed manually and fused post-reconstruction for basic material decomposition.
What is the typical reconstruction time for a full-volume scan at 2 µm resolution?
Using GPU-accelerated FDK reconstruction on a dual-NVIDIA A100 workstation, a 2000-projection scan (3072×3072) reconstructs into a 2048³ volume in approximately 8–12 minutes.
Does the system include remote diagnostics and service connectivity?
Yes—optional AlwaysCare Connect module provides encrypted remote monitoring, predictive maintenance alerts, and secure technician-assisted troubleshooting compliant with ISO/IEC 27001 information security protocols.
