Detailed Descriptions for the elements in the ImagingStudy resource.

ImagingStudy
Element IdImagingStudy
Definition

Representation of the content produced in a DICOM imaging study. A study comprises a set of series, each of which includes a set of Service-Object Pair Instances (SOP Instances - images or other data) acquired or produced in a common context. A series is of only one modality (e.g. X-ray, CT, MR, ultrasound), but a study may have multiple series of different modalities.

Control1..1
ImagingStudy.identifier
Element IdImagingStudy.identifier
Definition

DICOM Study Instance UID, and Accession Number.

NoteThis is a business identifer, not a resource identifier (see discussion)

Requirements

UID would be encoded using FHIR OID encoding recommendation. Study Instance UID is indicated with use of "official", accession with use of "secondary".

Unknown does not represent "other" - one of the defined statuses must apply. Unknown is used when the authoring system is not sure what the current status is.

ImagingStudy.modality
Element IdImagingStudy.modality
Definition

A list of all the series.modality values that are actual acquisition modalities, i.e. those in the DICOM Context Group 29 (value set OID 1.2.840.10008.6.1.19).

ImagingStudy.endpoint
Element IdImagingStudy.endpoint
Definition

The network service providing access (e.g., query, view, or retrieval) for the study. See implementation notes for information about using DICOM endpoints. A study-level endpoint applies to each series in the study, unless overridden by a series-level endpoint with the same Endpoint.connectionType.

Control0..*
TypeReference(Endpoint)
Requirements

Access methods for viewing (e.g., IHE’s IID profile) or retrieving (e.g., DICOM’s WADO-URI and WADO-RS) the study or the study’s series or instances. The study-level baseLocation applies to each series in the study, unless overridden in series by a series-level baseLocation of the same type.

Summarytrue
Comments

Typical endpoint types include DICOM WADO-RS, which is used to retrieve DICOM instances in native or rendered (e.g., JPG, PNG), formats using a RESTful API; DICOM WADO-URI, which can similarly retrieve native or rendered instances, except using an HTTP query-based approach; DICOM QIDO-RS, which allows RESTful query for DICOM information without retrieving the actual instances; or IHE Invoke Image Display (IID), which provides standard invocation of an imaging web viewer.
