Working with the DicomContextGroup Object

The Context Groups defined by the DICOM Content Mapping Resource (DCMR), which is specified by PS 3.16 of the DICOM Standard, are maintained by LEADTOOLS in an internal table. The CurrentContextGroup property of the ILEADDicomDS Interface specifies the currently selected Context Group in the Context Group Table, the DicomContextGroup object. LEADTOOLS provides the IDicomContextGroup dual interface for specifying Context Groups, which defines the following properties for specifying a Context Group:

$image\sqrblit.gif$ ContextIdentifier property: This property specifies the Context Identifier (0008,010F) of the Context Group (for example, "CID 2", "CID 82", "CID 3001", etc.). A Context Group is identified by its Context ID (CID). For a list of the Context IDs of the Context Groups maintained internally, refer to Context Identifiers.

$image\sqrblit.gif$ Name property: This property specifies the name of the Context Group (for example, "Anatomic Modifier", "Units of Measurement", "ECG Leads", etc.).

$image\sqrblit.gif$ Extensible property: This property specifies whether the Context Group is Extensible.

$image\sqrblit.gif$ ContextGroupVersion property: This property specifies the Context Group Version (0008,0106) of the Context Group. Refer to the DateTimeValues property for the properties specified by a DATETIMEVALUEItem object.
