Work Group 27 is focused on leveraging Web technologies and defining Web based extensions to DICOM that address the communication needs resulting from clinical use cases for medical image distribution, viewing and processing. These extensions should enable Web-based intra- and inter-enterprise communication and management of the medical imaging record and associated workflows; as well as facilitate integration with other healthcare IT systems. Work Group 27 also coordinates its work with other standards organizations such as HL7 and IHE, so that DICOM Web Services efficiently interoperate with other Web-based medical informatics standards.

Current Supplements, Work and Objectives:

  • Sup193 – Web Service Notifications – Public Comment
  • Working with WG-31 on DICOMweb Conformance Statement
  • Working with WG-20 II on FHIR imaging resources

Challenges and Opportunities (Environment):

  • Generalized notifications
  • Ongoing joint efforts with HL7 FHIR imaging objects and IHE Radiology
  • DICOM+JSON needs improvement
  • Request that STOW be extended to support single part payload
  • There may be interest in RESTful Modality Worklist
  • FHIR based solution
  • IHE Encounter Based Imaging Profile.

Future Roadmap and Objectives (Committee Direction):

  • Continue harmonizing our work with IHE and HL7 initiatives that are web based, so that images can be shared using the same approach as non-image documents.
  • Keep a eye on new emerging technologies in the scope intra- and cross-enterprise sharing of image information and patient medical context, and leverage these when applicable.
  • Maintain the working relationship with ISO TC 215
  • Maintain the working relationship with the IHE ITI and IHE Radiology domain committees
  • Maintain the working relationship with the HL7 Imaging Integration committee
  • Develop supplements for the current work items
