Detailed Description

An adapter to make multi-frame data look like multi-file data.

The vtkDICOMMetaDataAdapter object makes an enhanced multi-frame DICOM data set appear to be a series of data sets. Whenever the caller requests and attribute from a specific instance, the attribute is instead pulled from the PerFrame item for a specific frame. If constructed from a metadata object that is not an enhanced multi-frame dataset, it simply acts as a pass-through.

Constructor & Destructor Documentation

◆ vtkDICOMMetaDataAdapter() [1/2]

vtkDICOMMetaDataAdapter::vtkDICOMMetaDataAdapter ( vtkDICOMMetaData * meta )

Construct an adapter for the given meta data object.

If the provided meta-data is from an enhanced multi-frame data set, then the adapter will make it look like a series of data sets. If the provided meta-data is from a series of non-enhanced data sets, the adapter will act as a simple pass-through.

◆ vtkDICOMMetaDataAdapter() [2/2]

vtkDICOMMetaDataAdapter::vtkDICOMMetaDataAdapter	(	vtkDICOMMetaData *	meta,
		int	i
	)

Construct an adapter for one DICOM object instance.

If instance i of the provided meta-data is an enhanced multi-frame data set, make it look like a series.

Member Function Documentation

◆ Get() [1/2]

const vtkDICOMValue& vtkDICOMMetaDataAdapter::Get	(	int	idx,
		vtkDICOMTag	tag
	)		const

Get an attribute value for the specified file index.

For an enhanced multi-frame data set, this will search the PerFrame attributes, then the Shared attributes, and finally the basic data set attributes.

◆ Get() [2/2]

const vtkDICOMValue& vtkDICOMMetaDataAdapter::Get ( vtkDICOMTag tag ) const

Get an attribute value.

For an enhanced multi-frame data set, this will first try to retrieve the attribute from the SharedFunctionalGroupSequence.

◆ GetNumberOfInstances()

int vtkDICOMMetaDataAdapter::GetNumberOfInstances ( ) const

inline

Get the number of instances (i.e. files).

For an enhanced multi-frame data set, this will return the number of frames. For a non-enhanced data set, it returns the number of instances in the series.

◆ Has()

bool vtkDICOMMetaDataAdapter::Has ( vtkDICOMTag tag ) const

Check whether an attribute is present in the metadata.

For an enhanced multi-frame data set, this will search the Shared and PerFrameFunctionGroupSequence in addition to searching the basic data set attributes.

◆ ResolvePrivateTag()

vtkDICOMTag vtkDICOMMetaDataAdapter::ResolvePrivateTag	(	vtkDICOMTag	ptag,
		const std::string &	creator
	)

Resolve a private tag.
