Radiographic Film Digitization Services in India by A-Star Testing & Inspection convert legacy industrial X-ray and gamma-ray films into high-resolution digital DICONDE images — preserving inspection records, simplifying audit retrieval, and enabling enhanced defect interpretation through digital processing tools. We service refineries, petrochemical plants, fabrication shops, and EPC archives across India that hold decades of film records and need them migrated to a modern digital workflow.
Whether your film archive is 200 films or 200,000 films, our digitization workflow preserves image quality to ASME and ASTM standards, applies metadata indexing for fast retrieval, and delivers searchable digital archives ready for cloud storage or in-house QMS integration.
What Is Radiographic Film Digitization?
Radiographic film digitization is the process of scanning industrial radiographic films (X-ray or gamma-ray) using a calibrated film digitizer and converting them to high-bit-depth digital images that preserve the full density range and grey-scale information of the original film. Unlike consumer photo scanners, industrial film digitizers use laser or LED light sources with photomultiplier or CCD detection, calibrated to ASTM E2446 (System Performance) and ASTM E2007 (Image Quality Indicator).
The output is typically a 16-bit DICONDE-format file (Digital Imaging and Communications in Non-Destructive Evaluation) — the industrial equivalent of medical DICOM — that preserves all defect detail and supports enhanced viewing through digital tools (contrast adjustment, zoom, edge enhancement, density measurement).
Why Digitize Radiographic Films?
- Preservation — silver halide films degrade over time. Digitization preserves the inspection record indefinitely.
- Audit retrieval — searching a digital archive by weld ID, date, or inspector takes seconds. Searching a physical film archive takes hours.
- Enhanced interpretation — digital tools (contrast windowing, zoom, edge enhancement) reveal details that may have been overlooked on the original film viewer.
- Storage cost — film vaults require climate control. Digital archives sit on a server.
- Risk-Based Inspection (RBI) input — digitised historical films feed into modern integrity programmes for fitness-for-service and life-extension assessment.
- Regulatory compliance — Indian refineries, power plants, and pressure-vessel fabricators are increasingly required by audit regimes to retain inspection records in retrievable digital format.
Standards Our Film Digitization Process Complies With
- ASTM E2446 — Standard Practice for Manufacturing Characterization of Computed Radiography Systems
- ASTM E2698 — Standard Practice for Radiological Examination Using Digital Detector Arrays
- ASTM E2007 — Standard Guide for Computed Radiography
- ASTM E2339 — Standard Practice for Digital Imaging and Communication in Nondestructive Evaluation (DICONDE)
- ISO 14096-1, -2 — Non-destructive testing — Qualification of radiographic film digitisation systems
- EN 14096-2 — European equivalent
Our Film Digitization Workflow
- Asset survey — visit your film archive, count films, capture metadata structure (film bag IDs, weld IDs, project IDs)
- Quality grading — separate films into good (digitisable as-is), degraded (needs cleaning), and unrecoverable categories
- Cleaning and preparation — soft-cloth cleaning, careful handling per archival best practice
- Digitization — scanning at 16-bit greyscale, 50-micron resolution (or finer where required), DICONDE output
- QC verification — every 10th film cross-checked by ASNT Level III against original viewer interpretation; image quality verified against ASTM E2007 IQI
- Metadata indexing — every digital file tagged with weld ID, date, inspector, project, acceptance status
- Delivery — encrypted hard drive, cloud upload (S3/Azure), or integration into your in-house QMS — your choice

Frequently Asked Questions
What resolution do you scan films at?
Standard digitization is at 50-micron resolution (508 dpi) with 16-bit greyscale depth. For high-criticality applications (nuclear, aerospace), we scan at 25-micron (1016 dpi). The output meets ISO 14096 Class A requirements.
What format are the digitised files delivered in?
Native delivery format is DICONDE (Digital Imaging and Communication in Nondestructive Evaluation) — the ASTM E2339 industrial equivalent of medical DICOM. We can also deliver TIFF (16-bit, lossless) and JPEG2000 (lossless or controlled-loss) on request.
Can you handle large archive volumes?
Yes. Our digitization centre handles batch volumes from 200 films to 200,000+ films. For very large archives, we can deploy on-site digitization at your facility to avoid film transit risk.
Are degraded or damaged films recoverable?
Most degraded films can be partially or fully recovered through careful cleaning and high-bit-depth scanning. Films with severe physical damage (tears, deep scratches) may have data loss in localised areas — we report each affected film honestly and flag it for review.
Is my film data secure during digitization?
Yes. Films and digital files are handled under chain-of-custody documentation. For sensitive client data, we operate under signed NDA, with secure transit, isolated digitization workstations, and encrypted delivery media.
