Detailed Descriptions for the elements in the ImagingStudy resource.

Alternate Names
ImagingStudy
Element Id ImagingStudy
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.

Element Id ImagingStudy.endpoint
Definition

Type Reference ( 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.

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.
