When upgrading to IMPAX 6.5.1, all data stored in legacy Key Image Note tables is automatically migrated to new Key Image Note tables and registered. After the migration is complete, IMPAX 6.5 Clients can display the Key Image Notes for studies created prior to the upgrade.
The DICOM Object Creator process creates and registers KOSD DICOM objects. KOSD DICOM objects are created for migrated studies only when these studies are exported from IMPAX by transmit, PACS Store and Remember archiving, or CD Export. When Key Image Notes are created locally, KOSD DICOM objects are unnecessary, as the information is already stored in database tables. Remote sites require these objects.
A Task Scheduler registers KOSD DICOM objects that were created prior to upgrading to IMPAX 6.5, making the information in these objects available to the local IMPAX system. The Task Scheduler creates a REGISTER_KOSD job for each KOSD DICOM object that has not been registered in database tables. Each REGISTER_KOSD job is placed in the MVF_OBJECT_CREATOR queue. When the REGISTER_KOSD job is processed, a KOSD DICOM object is registered into the system, so that key images can be displayed on the Client.
 | Important! If the job responsible for either creating or registering the KOSD DICOM object fails for any reason (for example, a KOSD object received from a third-party system is not DICOM-compliant), any KOSD objects that are created for that study and then subsequently marked for deletion are removed from the Image area and are no longer visible to the user. However, because of the failed job, Autopilot Manager, which controls the timing of image deletion from cache, considers the job outstanding and the invisible objects are not deleted. If the study is then transmitted to another IMPAX system, the invisible objects are transmitted as well, resulting in a discrepancy in the number of objects between the two systems, and causing the invisible objects to be visible on the system the study was transmitted to. |
