Desktop integration for Healthcare Providers and Researchers

We maintain Cast Interface — open-source Pub/Sub desktop integration that connects viewers, worklists, and backend AI tools. It carries format-agnostic events and imaging payloads — including DICOM, NIfTI, FHIR, DICOMweb, openEHR, XDS.i manifests or custom data formats.

Visit the 3D Slicer cast extension documentation for installation, hub setup, resource servers, and workflows.

Cast Interface

Cast is an open-source offshoot of FHIRcast — a secure event hub that replaces brittle desktop file-drop integrations with WebSocket subscriptions shared across healthcare imaging clients.

What Cast enables

Capabilities

  • Multi-viewer sync

    Keep OHIF, VolView, Slim, and 3D Slicer aligned on the same study context over low-latency WebSocket events.

  • Binary DICOM transfer

    Publish and receive imaging payloads through the hub with multipart binary batches — no fragile file drops.

  • Resource servers & AI

    Connect backend agents such as TotalSegmentator so results reach the desktop without a round-trip to the archive.

  • Worklist & conference

    Drive ImagingStudy-open from a shared worklist and start cross-product conferences from any connected client.
