I am importing an STL file (couch, in green) as segmentation on top of a DICOM CT (which has its own contour, in gray). In the attached picture you see the three central CT slices, the CT contour (gray) and the STL file (green).
I would like to export the segmentation as a RTSTRUCT contour on top of this CT, even if it is outside the field of view of the CT. Thus, in the data hierarchy, I move the segmentation into the DICOM Study and then export.
That works well so far, with the exception that the green STL contour is clipped along the slice axis (not on the other axes). See on the second image, obtained when I reimport in Slicer the exported dicom.
I would like to ask for a feature (check-box advanced option) where one could enable saving contours outside of the first/last slice. I guess this should be possible as the RTSTRUCT contours are specified as 3D coordinates. Thus, one could add the out of range contours by adding them recursively to the last CT slice but using a different z coordinate.
Do you think this is doable? Thanks in advance.
