Objective
To load and visualize planning contours and planned dose distributions generated by Nucletron Oncentra Planning System in Slicer.
Approach, Plan
We plan to port existing Matlab and C++ codes into Slicer for reading the files generated by the Nucleotron Oncentra Planning System. In addition, we will have to implement new functionality from the Nucleotron specifications. We expect that we will be able to visualize the contours using the Plastimatch Extension Module.
Progress
We have integrated functionality into Slicer3d v 4 to read the US image data (i.e. greyscale) exported by the Nucleotron system in .l3d format. We have also implemented a command line module to convert the .l3d file into NIFTI files and raw binary files. If needed, a DICOM convert feature could be easily added.
Regarding the structure and dose planning information contained in .ldd format files – we have implemented functionality to read the contour data into Slicer3D. However, we have yet to implement visualization capability. Firstly, we would need convert the contours (which are in a polyline format) into label maps – and visualize them as volumes. Alternatively, we could directly visualize the polyline data by converting it into a surface mesh.
Also, integration of this functionality into Plastimatch is planned.
