  4. Summary • Instance Availability Notification –Option within the Scheduled Workflow Integration Profile: • Signals the Availability of Images or Other Evidence Objects • Provides Information about the Location of Images IHE Europe Workshop

  5. Background • Managing Actors (DSS/Order Filler, Post-Processing Manager, Report Manager) need to know when acquired evidence objects made it to the Archive • MPPS may be sent before objects are stored, and storage may fail • MPPS is not available to all “managers” • MPPS may fail or not be sent at all (media import) • Existing query mechanism forces “managers” to poll Image Manager/Archive for availability of Instances IHE Europe Workshop

  6. Interaction Diagram • Image Manager/Image Archive generates an Instance Availability Notification message and sends it to the DSS/Order Filler(optionally to other workflow managing actors: Post-Processing Manager, Report Manager) • Receiving actors process the information and decide upon further course of actions IHE Europe Workshop

  7. Image Manager Behavior • Image Manager shall send only one IAN message for each MPPS referencing at least one evidence object • Image Manager shall sent an IAN after it received ALL instances referenced in MPPS • Image Manager shall send IAN to the DSS/OF(optionally to other workflow managing actors) IHE Europe Workshop

  8. Receiving Actor Behavior • Actors being notified are expected to use IAN message contents for workflow management • Keep a list of references to instances and their location for later retrieval • Examples of internal actions: • The Department System Scheduler/Order Filler may update the procedure status internally, indicating that images for the procedure have been stored • The Post-Processing Manager may add or re-arrange items in a corresponding worklist • The Report Manager adds items to a corresponding worklist IHE Europe Workshop

  9. Additional Considerations • IAN is currently limited to the availability of a COMPLETE set of evidence objects resulting from an image acquisition • No message may be sent if complete object set never arrives • No message may be sent if objects arrive without a corresponding MPPS • Timing of IAN can vary significantly depending on timing of MPPS and object storage • IAN does not cover other availability statues such as: • Images pre-fetched • Non-availability status (instances moved to another location) • Report statuses IHE Europe Workshop

  10. Value Proposition • Enhanced Mechanism to Notify Instance Availabilityin “Real-Time“ • Information about the Location of Images and Access Time • Optimized Workflow Management –Knowing where instances reside and how to retrieve IHE Europe Workshop
