Orthovoltage treatment planning system

[cpinter]

Treatment planning system for orthovoltage RT, for treating skin lesions.

This will contain various file readers and converters, as well as a dose engine class that calls EGSnrc code after providing it the proper input.

• Duplicate VffFileReader module [2], call it DosxyzNrc3dDoseFileReader (Andras: please correct the name if you think it can be better)
  • Rename all files, all class names, etc to the new name. Read through the code carefully and change things as you go (name in license text, contributor, etc.)
  • The parameter defined in qSlicerVffFileReaderOptionsWidget won’t make sense in our case, but let’s leave it like that for now
• Add the module to SlicerRT: edit the CMakeLists.txt file [3] (build SlicerRT and make sure it compiles, then commit to your branch – I’ll give you more info)
• Edit the logic file [4] to read .3ddose files
  • Find a sample dose file here [5] (I just googled it and downloaded one I found in a ResearchGate discussion)
  • Check if the file complies with the specifications: Section 12 in [6]
  • Check out this Matlab reader script [7], see if it makes sense to port this to C++. Even if not, see what checks and verifications it makes, and build it into your code

Next task will be exporting plan and beam parameters that can be fed as input to the CCSEO EGSnrc engine.

Until we have access to an EGSnrc dose engine to test the development of this task, we will work on surface scanning:

• Use Artec Eva on a phantom and a painted lesion to get a surface scan
• Register surface scan to CT in Slicer (using ICP on subsampled surfaces)
• Contour lesion using Segment Editor
• Export to DICOM-RTSS

Surface scanning workflow has been developed by @anna-ilina, paper submitted to CARS 2018.

She is working on integrating ctcreate into the SlicerRT orthovoltage dose engine so that CTs can be automatically converted to the phantom format DOSXYZnrc requires.
