DICOM · Tag editor · Anonymizer · Viewer

Surgical control over every DICOM tag.

A native desktop workbench for editing metadata, anonymizing studies to HIPAA PS3.15, and inspecting volumes in 3D. Thousands of tags at 60 fps — and no PHI ever leaves your machine.

Capabilities

Everything you need to read, repair, and release imaging data.

Four core surfaces — the tag tree, the anonymizer, the viewer, and the audit trail — designed to handle real clinical and research workloads without compromise.

Tag editor

Thousands of tags. Zero dropped frames.

A fully virtualized tree renders the deepest nested sequences instantly. Filter by group, element, VR, or value — then bulk-edit across the entire selection and see exactly what changed.

  • 60 fps virtualization — scroll 10,000-element datasets with no lag.
  • Structured search — query (0010,*), a keyword, or any value substring.
  • Bulk edit — apply a value or rule to every matching tag at once.
  • Inline validation — VR conformance and type checks as you type.

HIPAA · PS3.15

Anonymize to the standard, not to a guess.

Apply DICOM PS3.15 Annex E confidentiality profiles with the exact option set your protocol requires. UIDs remap consistently across an entire cohort, and pixel-burned PHI and identifiable faces are removed.

  • Annex E profiles — Basic, Clean Pixel Data, Clean Descriptors, Retain Longitudinal, and more.
  • Consistent UID remapping — one patient stays one patient across every study.
  • Face defacing — strip identifiable facial geometry from head MR/CT volumes.
  • Private tag handling — keep, remove, or whitelist vendor blocks.

See the whole study, not one slice.

Reconstruct axial, sagittal, and coronal planes with synchronized crosshairs. Move a single reticle and all three planes follow. Window/level, zoom, and measure without ever leaving the app.

  • Synchronized crosshairs — one click locates the same voxel in every plane.
  • Window/level — right-drag to adjust W/L; left-drag to pan; scroll to zoom.
  • Measurement tools — distance, angle, and ROI statistics.

Audit & provenance

A cryptographic record of every change.

Every edit, anonymization, and export is logged and chained with session hashes — so you can prove exactly what was done to a dataset, and that nothing else was. Export the trail for IRB and compliance review.

  • Hash-chained log — tamper-evident session integrity.
  • Full provenance — original → derived lineage for every file.
  • Exportable — CSV / JSON trails for IRB and audit.
  • Non-destructive — originals are never modified in place.

Pixel operations

Crop, resample, reorient, and rescale into derived copies — the original series is never touched.

Format conversion

DICOM → NIfTI, PNG/TIFF frame export, and clean de-identified DICOM resends.

Conformance validation

Check datasets against IOD requirements and surface actionable, tag-level errors.

CLI & automation Coming soon

Desktop-only scriptable CLI for headless DICOM operations and pipeline integration.

Batch & cohorts Coming soon

Run any workflow across thousands of studies with live progress and full rollback.

Local-first by design

Runs entirely on-device — native desktop or the web app. Nothing is ever uploaded.

Supported workflows

Built for specific tasks, not a blank canvas.

Designed around real clinical and research tasks — each workflow below maps directly to features the app handles today. A sample across ten categories:

Anonymization 01
  • De-identify multi-center trial export
  • Strip private tags from vendor CT
  • Deface T1 MPRAGE before release
Editing 02
  • Correct Patient ID across a study
  • Fix wrong Modality / Body Part
  • Batch-set Institution Name
Restructuring 03
  • Split fused series by orientation
  • Merge multi-frame into one series
  • Renumber instances sequentially
Pixel ops 04
  • Crop to ROI for model input
  • Resample to isotropic 1 mm
  • Reorient to RAS / LPS
Conversion 05
  • DICOM → NIfTI for analysis
  • Export PNG frames for review
  • De-identified DICOM resend
Validation 06
  • IOD conformance check
  • Detect missing required tags
  • Verify UID consistency
Integration 07
  • Headless batch in CI pipeline
  • Route to PACS by rule
  • CLI anonymize on ingest
Modalities 08
  • Enhanced MR multi-frame
  • Whole-slide pathology (SM)
  • RT structure sets & dose
AI / ML 09
  • Build de-identified training corpus
  • Normalize orientation across sites
  • Export labels with provenance
Compliance 10
  • HIPAA Safe Harbor checklist
  • GDPR pseudonymization
  • IRB-ready audit export
These workflows represent the tasks dcmage is specifically designed to handle — not a wish list.
