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.
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.
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.
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.
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.
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 Planned · Pro
Desktop-only scriptable CLI for repeatable DICOM operations.
Batch & cohorts Planned · Pro
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.
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:
