Healthcare Data Tools

Free · Open source · 100% client-side

Healthcare data tools that run entirely in your browser

Parse HL7 v2.x messages, view and edit DICOM files, generate test data, and simulate modality worklists — with no installs, no accounts, and no PHI ever leaving your machine.

The toolkitSix tools, zero setup

Everything you need to debug, test, and learn HL7 v2.x and DICOM — each tool is a standalone page that works offline once loaded.

  • Medical Imaging

    DICOM Viewer & Tag Morph

    View DICOM studies across every major storage SOP class — CT, MR, US, XA, NM, PET, mammography, RT and more — with window/level, cine playback, and measurements. Edit tags inline or in batch and re-export valid DICOM.

    Launch tool
  • Test Data

    DICOM Toolbox

    Create, configure, and generate DICOM files from scratch, then inspect the result with the built-in tag reader. Ideal for testing DICOM implementations, building synthetic datasets, and learning the standard.

    Launch tool
  • Clinical Messaging

    HL7 v2.x Parser

    Paste any HL7 v2.x message for an instant segment-by-segment, field-by-field breakdown with names and descriptions from the standard. Understand your interface data at a glance.

    Launch tool
  • Data Validation

    HL7 Diff Checker

    Compare two HL7 messages side-by-side at the segment and field level. Spot exactly what changed between interface versions, vendor feeds, or environments.

    Launch tool
  • Modality Worklist

    MWL Simulator

    Simulate a DICOM Modality Worklist or query one as a C-FIND SCU. Test worklist integrations against a built-in dataset or connect to a real SCP.

    Launch tool
  • Workflow Integration

    DICOM → HL7 Order

    Read the tags from any DICOM file and generate a matching HL7 ORM^O01 radiology order message — bridging imaging and clinical messaging workflows.

AboutBuilt for healthcare integration work

These tools grew out of day-to-day interface engineering: debugging HL7 feeds, testing PACS and modality connections, and building synthetic data for demos and development. They're made for healthcare IT professionals, integration engineers, and students working with medical data standards.

Everything is plain HTML and JavaScript served as static files — there is no backend, no analytics, and no tracking. Because real messages and images often contain PHI, the tools are deliberately designed so that data never leaves the page.
