2. RT Import DicomRtImport DICOM plugin
RTDose: dose value scaling, unit name and color table
RTStructureSet: contour nodes are created and put in hierarchy
RTImage: custom planar image created and can be shown as textured plane in 3D

3. RT Import cont’d RTPlan: isocenters and beams are read and shown
MLC is not yet supported here, however works in External Beam Planning, porting needed (see External Beam Planning NA-MIC week project)
Not supported modalities
RTTreatmentSummaryRecord
RTIonPlan
RTIonBeamsTreatmentRecord
All supported modalities have Subject hierarchy roles and basic features (such as create dose)

5. Spatial Registration Object
3 different kinds of SRO:
Affine, fiducial and deformation
Current status
Affine and deformation import implemented
Affine export implemented
Affine round trip tested with Mim software
Deformation export in progress
Not integrated into subject hierarchy

6. DICOM export Language Similar mechanism – confidence values
Python: DICOM import is implemented in python
C++: DCMTK is available (more useful for import)
Similar mechanism – confidence values
DICOM module could handle basic things like create study or append to existing study

7. DICOM export cont’d
Plugins that depend on DICOM can override the basic method exporting their supported objects (series only)
Where to store additional information?
In Subject hierarchy? It handles the DICOM levels, so it seems to be a logical place
GUI should write this info in SH nodes

8. DICOM export cont’d 2 DICOM tag editor needed
Re-usable widget that allows editing DICOM tags (stored in prefixed node attributes) of a SH node
This widget appears in a collapsed box under the SH tree, and also in the export pop-up
Copy DICOM tags from (confirm overwrite)
Other SH node
Series in DICOM database
