Updating image set metadata - AWS HealthImaging

Updating image set metadata

Use the UpdateImageSetMetadata action to update image set metadata in AWS HealthImaging. You can use this asynchronous process to add, update, and remove image set metadata attributes, which are manifestations of DICOM normalization elements that are created during import. Using the UpdateImageSetMetadata action, you can also remove Series and SOP Instances to keep image sets in sync with external systems and to de-identify image set metadata. For more information, see UpdateImageSetMetadata in the AWS HealthImaging API Reference.

Note

Real-world DICOM imports require updating, adding, and removing attributes from the image set metadata. Keep the following points in mind when updating image set metadata:

  • Updating image set metadata creates a new version in the image set history. For more information, see Listing image set versions. To revert to a previous image set version ID, use the optional revertToVersionId parameter.

  • Updating image set metadata is an asynchronous process. Therefore, imageSetState and imageSetWorkflowStatus response elements are available to provide the respective state and status of an image set undergoing update. You cannot perform other write operations on a LOCKED image set.

  • If the UpdateImageSetMetadata action is not successful, call and review the message response element to see common errors.

  • DICOM element constraints are applied to metadata updates. The force request parameter allows you to update elements in cases where you want to override DICOM metadata constraints.

  • Set the force request parameter to force completion of the UpdateImageSetMetadata action. Setting this parameter allows the following updates to an image set:

    • Updating the Tag.StudyInstanceUID, Tag.SeriesInstanceUID, Tag.SOPInstanceUID, and Tag.StudyID attributes

    • Adding, removing, or updating instance level private DICOM data elements

Example 5: To add a private DICOM data element to an instance

The following update-image-set-metadata example shows how to add a private element to a specified instance within an image set. The DICOM standard permits private data elements for communication of information that cannot be contained in standard data elements. You can create, update, and delete private data elements with the UpdateImageSetMetadata action.

aws medical-imaging update-image-set-metadata \
    --datastore-id 12345678901234567890123456789012 \
