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 can have multiple series of different modalities. modality values.

Identifiers for Business identifiers assigned to this imaging study by the ImagingStudy such performer and/or other systems. These identifiers remain constant as the resource is updated and propagates from server to server. Typically this will include the DICOM Study Instance UID, and Accession Number. UID.

If Allows identification of the imaging study as it is known by various participating systems and in a way that remains consistent across servers. ImagingStudy.identifier SHALL include exactly one Study Instance UID value if one or more series elements element values are present in the ImagingStudy, then there shall be one DICOM Study UID identifier (see DICOM PS 3.3 C.7.2 . .)

Note: This is a business identifier, not a resource identifier (see discussion ). It is best practice for the identifier to only appear on a single resource instance, however business practices MAY occasionally dictate that multiple resource instances with the same identifier can exist - possibly even with different resource types. For example, multiple Patient and a Person resource instance might share the same social insurance number, or an accession number MAY be used to relate a Task, an ImagingStudy and a DiagnosticReport. See discussion under Imaging Study Implementation Notes for encoding of DICOM Study Instance UID. Accession Number should use ACSN Identifier type.

The current state of the ImagingStudy. imaging study. This is distinct from the status of any service request or task associated with the imaging study.

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.

To support grouped procedures (one Allows tracing of authorization for the imaging study supporting multiple ordered procedures, e.g. chest/abdomen/pelvis CT). and tracking whether proposals/recommendations were acted upon. If the ImagingStudy is associated with an Accession Number, this field SHOULD include a reference to that value in the form: identifier.value = (Accession Number Value) identifier.type = ACSN. A reference value pointing to a ServiceRequest resource is allowed but is not required.

One imaging study MAY be based on multiple ordered procedures, e.g. chest/abdomen/pelvis CT orders being fulfilled by a single imaging study.

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.

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 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.

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 metadata without retrieving the actual instances; or IHE Invoke Image Display (IID), which provides standard invocation of an imaging web viewer. instances.
