Constructor Detail

ImageLibrary

public ImageLibrary()

Construct an empty Image Library.

ImageLibrary

public ImageLibrary(AttributeList list)
             throws DicomException

Construct an Image Library by extracting it from an existing DICOM SR instance.

Searches the content tree for the Image Library CONTAINER content item.

Parameters:

list - the attributes comprising the DICOM SR instance containing the Image Library

Throws:

DicomException - if error in DICOM encoding

ImageLibrary

public ImageLibrary(ContentItem imageLibraryContainer,
                    AttributeList list)

Construct an Image Library by extracting it from an existing DICOM SR instance.

Parameters:

imageLibraryContainer - the content item that is the Image Library CONTAINER

list - the attributes comprising the DICOM SR instance containing the Image Library

ImageLibrary

public ImageLibrary(Set<File> files)
             throws IOException,
                    DicomException

Create an SR Image Library from a bunch of DICOM image instances.

Adds a new series (instance UID) to the existing study (instance UID).

Parameters:

files - the filenames and/or folder names of files containing the input image files

Throws:

DicomException - if error in DICOM encoding

IOException - if error reading a file

Method Detail

addContributingEquipmentSequence

protected void addContributingEquipmentSequence(AttributeList list)
                                         throws DicomException

Throws:

DicomException

addImage

public ImageLibrary.ImageLibraryEntry addImage(AttributeList list)
                                        throws DicomException

Create and add an SR Image Library entry derived from a DICOM image instance.

Requires that a SOP Instance UID be present in the supplied image instance, to be used to index the entries.

Parameters:

list - the list of attributes of the image instance

Returns:

the new ImageLibraryEntry added to this ImageLibrary, or null if no SOP Instance UID is present in the supplied image instance

Throws:

DicomException - if error in DICOM encoding

constructImageLibrary

protected void constructImageLibrary(ContentItem imageLibraryContainer,
                                     AttributeList list)

Construct an Image Library by extracting it from an existing DICOM SR instance.

Parameters:

imageLibraryContainer - the content item that is the Image Library CONTAINER

list - the attributes comprising the DICOM SR instance containing the Image Library

findImageLibraryContainer

public static ContentItem findImageLibraryContainer(ContentItem node)

Find the Image Library contained within an SR content tree.

The Image Library is identified by the ("111028","DCM","Image Library") concept name for the content item.

Parameters:

node - the content item to being the search at (e.g., the root node)

Returns:

the content item that is the Image Library CONTAINER

getAttributeList

public AttributeList getAttributeList()
                               throws DicomException

Throws:

DicomException

getCommonInstanceReferenceModuleReferencedSeriesSequence

public SequenceAttribute getCommonInstanceReferenceModuleReferencedSeriesSequence(String studyInstanceUID)
                                                                           throws DicomException

Throws:

DicomException

getHierarchicalEvidenceSequence

public SequenceAttribute getHierarchicalEvidenceSequence()
                                                  throws DicomException

Build a hierarchical evidence sequence for the current Image Library content.

This contains the Study and Series Instance UIDs and is required for most SR IODs.

Returns:

a CurrentRequestedProcedureEvidenceSequence listing all the referenced instances

Throws:

DicomException - if error in DICOM encoding

getHierarchicalSOPInstanceReferencesIndexedBySOPInstanceUID

protected Map<String,HierarchicalSOPInstanceReference> getHierarchicalSOPInstanceReferencesIndexedBySOPInstanceUID(AttributeList list)

                                        throws DicomException

Get the Image Library as an SR fragment.

Has side effect of adding the fragment to the parent if the parent is not null.

Returns:

a new ContainerContentItem with ImageContentItem children

Throws:

DicomException - if error in DICOM encoding

main

public static void main(String[] arg)

Create an SR Image Library from a bunch of DICOM image instances.

Adds a new series (instance UID) to the existing study (instance UID).

Parameters:

arg - the path for the SR Image Library output, then the filenames and/or folder names of files containing the input image files
