Aolong VISION90 Microfocus X-ray Imaging System for Small Animal and Seed In Vivo Analysis

Overview

The Aolong VISION90 is a benchtop microfocus X-ray imaging system engineered for high-resolution, non-destructive radiographic analysis in life science research. Operating on the principle of transmission X-ray radiography with geometric magnification, it utilizes a 5 µm focal spot X-ray source and a high-sensitivity, 16-bit digital flat-panel detector to achieve an effective in vivo spatial resolution of 3 µm under optimal geometric conditions. Unlike conventional radiography systems, the VISION90 integrates precise source–detector–sample geometry control, enabling quantitative densitometry, morphometric analysis, and longitudinal monitoring without sample sectioning or contrast agent administration. Its design prioritizes biosafety, regulatory compliance, and operational accessibility—making it suitable for core facilities, preclinical labs, and plant science laboratories where routine, low-dose, high-fidelity imaging of intact biological specimens is required.

Key Features

• Integrated lead-shielded cabinet meeting GBZ 138–2017 for occupational radiation safety—no external shielding required.
• Stainless-steel interior chamber for easy decontamination and long-term hygiene compliance in vivarium or seed lab environments.
• Intuitive workstation interface with dedicated acquisition and processing software—no prior radiography training needed for basic operation.
• Real-time image preview with adjustable kV/mA, exposure time, and frame averaging for optimized signal-to-noise ratio.
• Quantitative measurement tools: calibrated distance, area, angle, grayscale histogram, ROI-based density profiling.
• Pseudocolor mapping for enhanced visualization of subtle density gradients in soft tissue, bone, or seed endosperm.
• Configurable file management: experiment metadata (kV, exposure, magnification, filter), DICOM-compatible export, PDF report generation, and audit-ready log files.
• Modular mechanical stage with motorized Z-axis and precision XYZ translation—enabling multi-angle projection and automated tilt-series acquisition.

Sample Compatibility & Compliance

The VISION90 supports a broad spectrum of intact biological and material specimens up to 15 × 10 cm in lateral dimension and ≤12 cm in height (with optional stage extension). Validated applications include live mice and rats (anesthetized, ventilated, or restrained), excised organs (e.g., lungs, femurs, calvaria), embryonic specimens, whole seeds (e.g., Arabidopsis, maize, soybean), dental models, fish skeletons, and paraffin-embedded tissue blocks. The system conforms to ISO 15801:2016 (digital imaging archival integrity), supports GLP-compliant documentation workflows, and enables traceable calibration via NIST-traceable step wedges. While not a medical device per FDA 21 CFR Part 820, its radiographic output meets ASTM E2737–22 standards for non-destructive evaluation of biological composites and porous structures.

Software & Data Management

The bundled VisionSuite™ software provides a unified platform for acquisition, reconstruction (2D projection only), annotation, measurement, and export. It supports DICOM 3.0 export for PACS integration and TIFF/PNG/AVI export for publication-grade figures. All acquisitions are timestamped and linked to user-defined experimental protocols. Audit trails record operator ID, parameter changes, image annotations, and export events—fully compliant with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). Raw projection data is stored in HDF5 format to preserve bit-depth fidelity and enable future reprocessing with third-party tools (e.g., ImageJ/Fiji, Python-based scikit-image pipelines).

Applications

• Small animal phenotyping: Longitudinal assessment of bone mineral density (BMD), fracture healing, osteolytic lesions, lung aeration patterns, and vascular calcification.
• Seed viability screening: Detection of embryo integrity, fungal hyphae, insect larvae, and endosperm degradation without germination.
• Dental and craniofacial research: High-contrast imaging of dentin-enamel junctions, root canal morphology, and orthodontic appliance fit.
• Pre-microCT triage: Rapid identification of promising candidates for downstream synchrotron or lab-based µCT scanning—reducing instrument queue time by >40%.
• Histopathology support: Verification of decalcification endpoint in bone biopsies; localization of microcalcifications in breast tissue sections prior to sectioning.
• Non-biological QA: Void detection in solder joints, porosity analysis in castings, and dimensional verification of MEMS devices.

FAQ

Is the VISION90 suitable for longitudinal in vivo imaging of awake rodents?
No—while designed for low-dose imaging, it requires physical immobilization. Anesthesia-compatible stages and thermoregulated platforms are available as optional accessories.
Does the system support tomographic reconstruction?
No—the VISION90 is a 2D radiographic platform. For 3D tomography, Aolong offers complementary µCT systems (e.g., VISION-CT series) with integrated reconstruction engines.
Can I import custom measurement protocols into VisionSuite™?
Yes—users may define and save reusable measurement templates (e.g., “femur cortical thickness,” “seed air-space fraction”) with preset ROIs, thresholds, and export formats.
What regulatory documentation is provided for facility audits?
Each unit ships with a Factory Calibration Certificate, Radiation Safety Test Report (per GBZ 138–2017), Software Validation Summary (IQ/OQ documentation available upon request), and CE Declaration of Conformity (Class I Medical Device, Annex II).
Is remote support and software update capability included?
Yes—VisionSuite™ includes secure HTTPS-based remote diagnostics and quarterly firmware/software updates delivered via encrypted download portal.
