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.

Other identifiers Identifiers for the study. ImagingStudy such as DICOM Study Instance UID, and Accession Number.

If one or more series elements are present in the ImagingStudy, then there shall be one DICOM Study UID identifier (see DICOM PS 3.3 C.7.2 .

See discussion under Imaging Study Implementation Notes for encoding of DICOM Study Instance UID. Accession Number should use ACSN Identifier type.

Availability The current state of study (online, offline, or nearline). the ImagingStudy.

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.

A list of all the Series.ImageModality 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).

The patient imaged in subject, typically a patient, of the imaging study.

QA phantoms can be recorded with a Device; multiple subjects (such as mice) can be recorded with a Group.

The encounter or episode at healthcare event (e.g. a patient and healthcare provider interaction) during which the request this ImagingStudy is initiated. made.

This will typically be the encounter the event occurred within, but some events may be initiated prior to or after the official completion of an encounter but still be tied to the context of the encounter (e.g. pre-admission test).

Date and time the study started.

A list of the diagnostic requests that resulted in this imaging study being performed.

To support grouped procedures (one imaging study supporting multiple ordered procedures, e.g. chest/abdomen/pelvis CT).

The requesting/referring physician.

Who read the study and interpreted the images or other content.

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

Number of Series in the Study. This value given may be larger than the number of series elements this Resource contains due to resource availability, security, or other factors. This element should be present if any series elements are present.

Number of SOP Instances in Study. This value given may be larger than the number of instance elements this resource contains due to resource availability, security, or other factors. This element should be present if any instance elements are present.

A reference to the performed Procedure. The procedure which this ImagingStudy was part of.

The code for the performed procedure type.

The principal physical location where the ImagingStudy was performed.

Ties the event to where the records are likely kept and provides context around the event occurrence (e.g. if it occurred inside or outside a dedicated healthcare setting).

Description of clinical condition indicating why the ImagingStudy was requested.

Indicates another resource whose existence justifies this Study.

Per the recommended DICOM mapping, this element is derived from the Study Description attribute (0008,1030). Observations or findings about the imaging study should be recorded in another resource, e.g. Observation, and not in this element.

The Imaging Manager description of the study. Institution-generated description or classification of the Study (component) performed.

Each study has one or more series of images or other content.

Formal identifier The DICOM Series Instance UID for this the series.

DICOM Series Instance UID.

See DICOM PS3.3 C.7.3 .

The numeric identifier of this series in the study.

The modality of this series sequence.

A description of the series.

Number of SOP Instances in the Study. The value given may be larger than the number of instance elements this resource contains due to resource availability, security, or other factors. This element should be present if any instance elements are present.

The network service providing access (e.g., query, view, or retrieval) for this series. See implementation notes for information about using DICOM endpoints. A series-level endpoint, if present, has precedence over a study-level endpoint with the same Endpoint.type. Endpoint.connectionType.

Access methods for retrieving (e.g., DICOM’s WADO-URI and WADO-RS) the series or the series’ instances. A baseLocation specified at the series level has precedence over a baseLocation of the same type specified at the study level.

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; and DICOM QIDO-RS, which allows RESTful query for DICOM information without retrieving the actual instances.

The anatomic structures examined. See DICOM Part 16 Annex L (http://dicom.nema.org/medical/dicom/current/output/chtml/part16/chapter_L.html) for DICOM to SNOMED-CT mappings. The bodySite may indicate the laterality of body part imaged; if so, it shall be consistent with any content of ImagingStudy.series.laterality.

The laterality of the (possibly paired) anatomic structures examined. E.g., the left knee, both lungs, or unpaired abdomen. If present, shall be consistent with any laterality information indicated in ImagingStudy.series.bodySite.

The specimen imaged, e.g., for whole slide imaging of a biopsy.

The date and time the series was started.

The physician or operator (often the radiology technician) Indicates who or what performed the series. series and how they were involved.

The performer is recorded at the series level, since each series in a study may be performed by a different practitioner, performer, at different times, and using different devices. A series may be performed by multiple practitioners. performers.

If the person who performed the series is not known, their Organization may be recorded. A patient, or related person, may be the performer, e.g. for patient-captured images.

Distinguishes the type of involvement of the performer in the series.

Allows disambiguation of the types of involvement of different performers.

Indicates who or what performed the series.

A single SOP instance within the series, e.g. an image, or presentation state.
