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.

Formal identifier for the study.

Accession Number is an identifier related to some aspect of imaging workflow and data management. Usage may vary across different institutions. See for instance IHE Radiology Technical Framework Volume 1 Appendix A .

Other identifiers for the study.

Availability of study (online, offline, or nearline).

A list of all the Series.ImageModality 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 subject, typically a patient, of the imaging study.

QA phantoms can be recorded with a Device; multiiple subjects 9such as mice) can be recorded with a Group.

The encounter or episode at which the request is initiated.

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.

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 code for the performed procedure type.

Description of clinical condition indicating why the ImagingStudy was requested.

Institution-generated description or classification of the Study performed.

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

Formal identifier for this series.

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.

Availability of series (online, offline or nearline).

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.

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) who performed the series.

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

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

Formal identifier for this image or other content.

The number of instance in the series.

DICOM instance type.

The description of the instance.

Particularly for post-acquisition analytic objects, such as SR, presentation states, value mapping, etc.
