DICOM · Tag editor · Anonymizer · Viewer

Surgical control over every DICOM tag.

A DICOM workbench for editing metadata, anonymizing studies to HIPAA PS3.15, and inspecting volumes in 3D. Runs in your browser or as a native Mac app, and processes studies on your own 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 — built for trial curation, metadata repair, and research workloads.

Tag editor

Find and edit any tag, including nested sequences.

The tag tree opens the whole file at once, nested sequences included. Filter by group, element, VR, or value — then edit any tag and see exactly what changed.

  • Fast scrolling — stays responsive on files with 10,000 tags.
  • Structured search — query (0010,*), a keyword, or any value substring.
  • Targeted edits — retype, remap, or clear individual tags with live diff.
  • Inline validation — VR conformance and type checks as you type.

HIPAA · PS3.15

Apply PS3.15 profiles and see each rule before export.

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

  • Built-in profiles — Basic, +Pixel, +Descriptors, HIPAA Safe Harbor, Teaching, and fully custom rules.
  • 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.

3D MPR viewer

Three synchronized planes through the volume.

Reconstruct axial, sagittal, and coronal planes with synchronized crosshairs. Move a single reticle and all three planes follow. Window/level, zoom, and measure in the same view.

  • 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 complete record of every change.

Every edit, anonymization, and export is logged and chained with SHA-256 session hashes — a complete, ordered record of what was done to a dataset that you can export for IRB and compliance review.

  • Hash-chained log — SHA-256 hash chain over the session log.
  • 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 stays as it is.

Format conversion

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

Conformance validation

Check datasets against IOD requirements and report which tags fail.

CLI & automation

Desktop-only scriptable CLI for repeatable DICOM operations.

Batch & cohorts

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

Local-first by design

Core DICOM work stays on your device in the web app and desktop app. Data is sent only when you choose to submit feedback.

Supported workflows

Built for specific tasks, not a blank canvas.

Designed for real-world imaging engineering tasks — each workflow below maps directly to features the app handles today. A sample across twelve categories:

De-identification 01
  • Multi-center trial PHI removal
  • Safe Harbor 18-identifier scrub
  • Vendor private tag cleanup
Pseudonymization & Pixel PHI 02
  • Reversible key-vault mapping
  • Face defacing for head MR/CT
  • Retain longitudinal temporal info
Patient & Study Demographics 03
  • Correct patient name
  • Fix DOB and sex
  • Correct StudyDescription and codes
Series, UIDs & Identity 04
  • Rename and reorder series
  • UID regeneration for derived copies
  • Set Institution and operator tags
Study Restructuring 05
  • Split fused series by orientation
  • Merge studies and series
  • Purge scouts, duplicates, corrupt instances
Spatial Pixel Operations 06
  • Crop to anatomical ROI
  • Resample to isotropic 1 mm
  • Reorient axial / sagittal / coronal
Pixel Processing 07
  • Window / level baking
  • Bit-depth conversion
  • Annotation burn-in and MPR export
Format Conversion 08
  • DICOM ↔ NIfTI
  • Export PNG / TIFF frames
  • DICOMDIR generation
Validation & QA 09
  • IOD conformance per modality
  • Missing required tags report
  • Diff two studies or files
Structured Reports & RT 10
  • Structured Report editing
  • RTSTRUCT contour editing
  • RTDOSE parameter scaling
Advanced Imaging & Waveforms 11
  • ECG waveform visualization
  • Whole-slide imaging inspection
  • Encapsulated PDF / STL extraction
Audit & Provenance 12
  • SHA-256 hash-chained audit trail
  • Tamper-detection re-verification
  • IRB-ready litigation export
These workflows represent the tasks dcmage is specifically designed to handle — not a wish list.
