Functional status A selection of DICOM SOP instances and/or frames within a single Study and Series. This might include additional specifics such as an image region, an Observation UID or a Segmentation Number, allowing linkage to an Observation Resource or transferring this information along with the ImagingStudy Resource.

A unique identifier assigned to this imaging selection.

Allows imaging selections to be distinguished and referenced.

This is a business identifier, not a resource identifier -- see discussion under Business Identifiers .

The current state of the ImagingSelection resource. This is not the status of any ImagingStudy, ServiceRequest, or Task resources associated with the ImagingSelection.

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.

The patient, or group of patients, location, device, organization, procedure or practitioner this map: 2 tests imaging selection is about and into whose or what record the imaging selection is placed.

The date and time this imaging selection was created.

Selector of the instances – human or machine.

Distinguishes the type of involvement of the performer.

Allows disambiguation of the types and involvement of different performers.

Author – human or machine.

A list of the diagnostic requests that all execute ok. resulted in this imaging selection being performed.

Classifies the imaging selection.

Used for filtering what imaging selections are retrieved and displayed.

Reason for referencing the selected content.

Knowing what kind of observation is being made is essential to understanding the observation.

All tests pass round-trip testing code-value and, if present, component.code-component.value pairs need to be taken into account to correctly understand the meaning of the observation.

The Study Instance UID for the DICOM Study from which the images were selected.

DICOM Study Instance UID. Required unless frameOfReferenceUid and 1 r3 resources imageRegion are invalid (0 errors). present and instance is not present.

See DICOM PS3.3 C.7.2 .

The imaging study from which the imaging selection is made.

The network service providing retrieval access to the selected images, frames, etc. See implementation notes for information about using DICOM endpoints.

Access methods for retrieving (e.g., DICOM’s WADO-URI and WADO-RS) the selected images, frames, etc.

Typical endpoint types include DICOM WADO-RS, which is used to R4 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.

The Series Instance UID for the DICOM Series from which the images were selected.

DICOM Series Instance UID. Required unless frameOfReferenceUid and imageRegion are present and instance is not present.

See DICOM PS3.3 C.7.3 .

The Series Number for the DICOM Series from which the images were selected.

DICOM Series Number.

See DICOM PS3.3 C.7.3 .

The Frame of Reference UID identifying the coordinate system that conveys spatial and/or temporal information for the selected images or frames.

DICOM Frame of Reference UID. Required if studyInstanceUid and seriesInstanceUid are not present.

See DICOM PS3.3 C.7.4.1 .

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 R3 SNOMED-CT mappings.

The actual focus of an observation when it is not the patient of record representing something or someone associated with the patient such as a spouse, parent, fetus, or donor. For example, fetus observations in a mother's record. The focus of an observation could also be an existing condition, an intervention, the subject's diet, another observation of the subject, or a body structure such as tumor or implanted device. An example use case would be using the Observation resource to capture whether the mother is trained to change her child's tracheostomy tube. In this example, the child is the patient of record and the mother is the focus.

An imaging selection may reference a DICOM resource that itself references other DICOM resources. e.g. a presentation state references a set of source images or frames.

Each imaging selection includes one or more selected DICOM SOP instances.

Required if the the selection does not include all instances in the specified series.

The SOP Instance UID for the selected DICOM instance.

DICOM SOP Instance UID.

See DICOM PS3.3 C.12.1 .

The Instance Number for the selected DICOM instance.

DICOM Instance Number.

See DICOM PS3.3 C.7.6.1 . Note: A multiframe instance has a single instance number with each frame identified by a frame number.

The SOP Class UID for the selected DICOM instance.

DICOM SOP Class UID.

See DICOM PS3.3 C.12.1 .

Selected subset of the SOP Instance. The content and format of the subset item is determined by the SOP Class of the selected instance. May be one of: - A list of frame numbers selected from a multiframe SOP Instance. - A list of Content Item Observation UID values selected from a DICOM SR or other structured document SOP Instance. - A list of segment numbers selected from a segmentation SOP Instance. - A list of Region of Interest (ROI) numbers selected from a radiotherapy structure set SOP Instance.

Each imaging selection instance or frame list might includes an image region, specified by a region type and a set of 2D coordinates. If the parent imagingSelection.instance contains a subset element of type frame, the image region applies to all conversions frames in the subset list.

Shall not be present if the parent imagingSelection.instance is not an image.

Specifies the type of image region.

See DICOM PS3.3 C.10.5.1.2 .

The coordinates describing the image region. Encoded as a set of (column, row) pairs that denote positions in the selected image / frames specified with sub-pixel resolution. The origin at the TLHC of the TLHC pixel is 0.0\0.0, the BRHC of the TLHC pixel is 1.0\1.0, and the BRHC of the BRHC pixel is the number of columns\rows in the image / frames. The values must be within the range 0\0 to the number of columns\rows in the image / frames.

The number of values must be a multiple of two.

For a description of how 2D coordinates are encoded, see DICOM PS3.3 C.18.6 .

Each imaging selection might includes a 3D image region, specified by a region type and a set of 3D coordinates.

Requires that the ImagingSelection.frameOfReferenceUid element is present.

Specifies the type of image region.

See DICOM PS3.3 C.18.9.1.2 .

The coordinates describing the image region. Encoded as an ordered set of (x,y,z) triplets (in mm and may be negative) that define a region of interest in the patient-relative Reference Coordinate System defined by ImagingSelection.frameOfReferenceUid element.

The number of values must be a multiple of three.

For a description of how 3D coordinates are encoded, see DICOM PS3.3 C.18.9 .
