DICOM support for AWS HealthImaging

AWS HealthImaging supports specific DICOM elements and transfer syntaxes. Familiarize yourself with the supported Patient, Study, and Series level DICOM data elements, as HealthImaging metadata keys are based on them. Before you start an import, verify that your medical imaging data is compliant with HealthImaging's supported transfer syntaxes and DICOM element constraints.

Supported SOP classes

With AWS HealthImaging, you can import DICOM P10 Service-Object Pair (SOP) instances encoded with any SOP class UID, including retired and private. All private attributes are also preserved.

Metadata normalization

When you import your DICOM P10 data into AWS HealthImaging, it is transformed into image sets that are comprised of metadata and image frames (pixel data). During the transformation process, HealthImaging metadata keys are generated based on a specific version of the DICOM standard. HealthImaging currently generates and supports metadata keys based on the DICOM PS3.6 2022b Data Dictionary.

AWS HealthImaging supports the following DICOM data elements at the Patient, Study, and Series levels.

Note

For a detailed description of each Patient level element, see the Registry of DICOM Data Elements.

DICOM element constraints

AWS HealthImaging applies DICOM element constraints when you import data and update image set metadata attributes. Both import and metadata update constraints are listed below.

When importing your medical imaging data into AWS HealthImaging, max length constraints are applied to the following DICOM elements. To achieve a successful import, ensure that your data does not exceed the max length constraints.

DICOM import constraints

When using UpdateImageSetMetadata to update metadata attributes in AWS HealthImaging, the following DICOM element constraints are applied.

  • Cannot update or remove private attributes on Patient/Study/Series/Instance level attributes unless the update constraint applies to both updatableAttributes and removableAttributes

  • Cannot update the following AWS HealthImaging generated attributes: SchemaVersion, DatastoreID, ImageSetID, PixelData, Checksum, Width, Height, MinPixelValue, MaxPixelValue, FrameSizeInBytes

  • Cannot update the following DICOM attributes: Tag.PixelData, Tag.StudyInstanceUID, Tag.SeriesInstanceUID, Tag.SOPInstanceUID, Tag.StudyID

  • Cannot update attributes with VR type SQ (nested attributes)

  • Cannot update multivalued attributes

  • Cannot update attributes with values that are not compatible with the attribute VR type

  • Cannot update attributes which are not considered valid attributes according to the DICOM standard

  • Cannot update attributes across modules. For example, if a Patient level attribute is given at the Study level in customer payload request, the request can be invalidated.

  • Cannot update attributes if the associated attribute module is not present in existing ImageSetMetadata. For example, you are not allowed to update attributes for a seriesInstanceUID if the Series with seriesInstanceUID is not present in existing image set metadata.
