Return the required DicomAttribute within a specified functional group within a DicomDataSet If DicomAttribute is not present in the specified DicomDataSet, it searches amongst the root level attributes

Syntax

public DicomAttribute FunctionalGroupOrRootLevelAttribute( 
   Keyword FunctionalAttribute,
   int Frame,
   Keyword keyword
)

public:
DicomAttribute^ FunctionalGroupOrRootLevelAttribute( 
   Keyword FunctionalAttribute,
   int Frame,
   Keyword keyword
)

'Declaration
 
Public Overloads Function FunctionalGroupOrRootLevelAttribute( _
   ByVal FunctionalAttribute As Keyword, _
   ByVal Frame As Integer, _
   ByVal keyword As Keyword _
) As DicomAttribute

'Usage
 
Dim instance As DicomDataSet
Dim FunctionalAttribute As Keyword
Dim Frame As Integer
Dim keyword As Keyword
Dim value As DicomAttribute
 
value = instance.FunctionalGroupOrRootLevelAttribute(FunctionalAttribute, Frame, keyword)

Parameters

FunctionalAttribute: The keyword of the requested dataset
Frame: The frame number to which the dataset should apply
keyword: The keyword of the requested attribute within the dataset

Return Value

The requested DicomAttribute

Remarks

The enhanced DICOM multi-frame objects (e.g. enhanced CT and MRI) allow many attributes to be held in functional group macros, which may be either:

The same for all frames - in the "Shared Functional Groups Sequence" (5200,9229)
Different for different frames - in the "Per-frame Functional Groups Sequence" (5200,9230)

This method allows an attribute to be retrieved from the chosen dataset, irrespective of which sequence it is in. Note that the DicomObjects.Enums.Keyword used to identify the functional group is independent of the DicomObjects.Enums.Keyword of individual attributes within that DataSet.

Requirements

Target Platforms: .NET CLR 4.0 or higher
