Hi everyone,

  I'd like to share a plugin I've been developing: RIS Study Finder.

  What it does:

  It allows your RIS (or any external system) to send an accession number to Horos via XML-RPC or URL scheme, and the plugin automatically:

  1.   Checks if the study exists in the local database  
  2. If not found, retrieves it from your PACS via C-GET
  3. Opens the study in the browser

  The whole flow is transparent — one click in the RIS and the study appears in Horos.

  Key features:

  - Works with both findStudy (local-first + remote fallback) and retrieveStudy (direct PACS query)

  •  Supports multiple accession numbers in a single call 
  • Background retrieval with progress indicator
  • Universal binary (Apple Silicon + Intel) - macOS 10.13+
  • Signed and notarized by Apple

  Integration example:

  osirix://?methodName=findStudy&accessionNumber=123456&server=MY_PACS

Or via standard XML-RPC to the Horos HTTP server.

  Website & documentation:

  https://risstudyfinder.com

  Download:

  https://github.com/lakecabin/risstudyfinder/releases/latest

  The plugin is commercially licensed (starting at $99/year for individual use). I'm a developer, and I built this to solve a real workflow problem in one specific clinic— switching between the RIS and manually searching for studies in Horos was eating up time.

I'd love to hear feedback from anyone who integrates Horos with a RIS. Happy to answer any questions about setup or the XML-RPC interface.

  Cheers,

  Alberto
