Overview
Manifest Profiles

The imaging manifest represents a summary of the data stored in a DICOM imaging study. In document based deployments, it is the 'document' that is searched for and provides the URL's that allow download of the imaging content. It is the data that is provided by a PACS system. The figure below presents an overview of the data that is part of the imaging-manifest.

In order to keep the diagram readable, not all references are included.

The manifest is a FHIR bundle that includes the ImagingStudy resource and at least one Endpoint. The Endpoint resources contain the information that allows the client to access the DICOM data. The current model identifies two different Endpoints. One that defines an DICOMweb-WADO which will allow download of the imaging data as well as extraction of thumbnails and retrieve the image data in other formats (e.g., jpeg). The other Endpoint defines the information needed to launch an IHE-IID based viewer.

Besides the ImagingStudy and Endpoint resources, it is also recommended to include additional resources that reflect information present in DICOM such as information on the patient, performer, procedure and imaging device.

The mapping from DICOM to these resources is defined in the mapping sections of the resources.
