RESTful DICOM Services

Medical Connections has implemented all 3 DICOM Web Services based on the DICOM Standard part 18.

All 3 services share the same underlying DicomServer, and this server is shared with the longstanding DIMSE based server, so it should for instance be possible to send an instance via STOW, and then retrieve via C-GET or the equivalent in reverse with C-STORE & WADO-RS.

Current stage of Development: Alpha

  • Although majority of the functions are supported, some remain to be implemented.
  • Internal testing starting on the 26th of September, 2014. All 3 services are live online for public testing and comments.
  • The main purpose of the current service is to allow others to check whether our interpretation of the standard agrees with theirs, and to identify any discrepancies, which should be reported to support@medicalconnections.co.uk
