[ITK] [ITK-users] RT Structure Files Have Negative Indexes

[Andras Lasso]

You might also use 3D Slicer with SlicerRT extension (www.slicerrt.org<http://www.slicerrt.org>) to import all kinds of RT data - including structure sets - and save them as binary label maps or surfaces that are easy to load using ITK.

Subject: [ITK] [ITK-users] RT Structure Files Have Negative Indexes


Hello,



I am trying to extract RT structure files into Niftii maps using the program found at http://www.insight-journal.org/browse/publication/887.



I have compiled it, and it runs successfully with the test data, yielding correct masks.  I then tried to run it on data given to me by a colleague.  The output shows there are some negative slice indexes such as:



Inserting region with 551 points into slice: -122


It also complains about contour points being outside the boundary, probably due to the negative indexes.



I am attaching the output.  I am not completely sure I can attach the RT file yet, as it is actual patient data.  I can find out and do so if that helps.  I don't know anything about RT structure files yet.  Does anyone have ideas of what I can tell my colleague who generated the files?



Thanks,

Jared
