Hello,

I am currently investigating the possibility of implementing Slicer RT as part of a Clinical protocol for the comparison of Proton and Cyberkinife treatment plans for liver cancer.

Part of the analysis process is to perform robost evaluation, whereby certiain aspect of the beams for the plan are adjusted and the dose is recalculated to simulate a number of worst case scenarios.

I believe such an analysis should be possible with slicer however when I load the DICOM files the beam data does not appear to be available for manipulation.

I have attached a screen shot of the warnings reported by Slicer when using the advance view of the DICOM load module. Im not exactly sure what the message means and if it could be related to the beam data being unavailable.

any assistance on this issue will be greatly appreciated,

thanks,  
Samuel

The first screenshot contains all the loadables offered by _all_ the DICOM plugins, most of which are not selected for loading. If you scroll up, then you’ll see the selected ones checked. Those are the ones that are loaded.

Can you please post a screenshot about the contents of the Subject hierarchy tree in the Data module after loading?  
And if you could look at the log (About / Report a problem) after loading and find any errors, those would be interesting to see as well. Thanks.

Also please note that SlicerRT currently cannot handle MLCs or arcs, only simple square beams. The infrastructure for MLCs is there, but never worked properly so it would need some work.

Thanks for the promt reply

I have attached screen shots of the subject hierarchy and error log.

I can also send a text of the log file is it helps?

Thanks,

Thanks for the screenshots. It seems that no plan or beam data is imported whatsoever.

Regarding the log, unfortunately only the info and warning messages are shown and not the errors which would be the interesting part.  
Yes please, go to About / Report an error in the menu after loading this dataset, and send us the log, or at least the parts that contain errors. Thanks

Thanks for the log! It does not say anything about failed beam data loading. Is it possible for you to share an anonymized dataset which you have this problem with? Then I’ll try to reproduce the issue.

I am happy to share the anonymized dataset,  
However could you please inform me as to the best means to share the data.

Cheers,

Whatever you normally prefer. Many times we use Dropbox/OneDrive/GDrive, but for some people a server hosted by their institution is easier. The data is for testing and bugfixing purposes only, so temporary storage is completely fine. Thanks!

I did some digging and it turns out that my hunch was right: the type of plan simply isn’t supported yet, see

> <https://github.com/SlicerRt/SlicerRT/blob/master/DicomRtImportExport/Logic/vtkSlicerDicomRtImportExportModuleLogic.cxx#L1689>

  
(the plan in your dataset has the SOP class UID of ion plans).

If you have some time, adding it shouldn’t be too hard I think. Just follow the existing example (RTPlanStorage) and the corresponding section of the DICOM standard. @gcsharp what do you think?  
If you decide to go for it, I’m happy to help!

RT Ion Plan shares some overlap with RT Plan, yes, I think it should not be too difficult.

Thanks for diagnosing the problem,

I would love to have a go at adding it, but i think will need a lot of help. My programing experience has been mainly limited to Matlab, but currently recieving training on Python programing . So any assistance will be much appreciated.

Excellent! I think you can help a lot in the DICOM side of things.

I’ll create a branch on GitHub for this and add placeholders where the proton/ion part needs to go so that you just need to fill in some gaps in the code. I’ll also point to examples you can copy-paste-modify to get the ion part working.

Please follow [this GitHub issue](https://github.com/SlicerRt/SlicerRT/issues/25). I’ll describe the steps there. Thanks a lot in advance!
