[Insight-users] Creating an approximate cross-section of a RT

[Jason.Dowling at csiro.au]

The approach in the paper will enable you to generate a discretized binary image of a contoured ROI with the same resolution as a supplied input volume - the ROI having been obtained from the RT treatment planning system.
The RT structures are just a list of points in real space (i.e. continuous space) relative to a defined origin. The origin should be the same as the image's origin - or their relative position should be known.

 Hope this helps.

Cheers,
Jason

The problem with the approach in the paper is that RT structure contours can have arbitrary resolution.

Hi Xiaofeng,

You can use the code from this Insight Journal paper: http://www.insight-journal.org/browse/publication/701 to read the DICOM-RT structures into a binary volume.  An easy way to then visualize the different orientations of the ROI is to load it into ITK-SNAP ( http://www.itksnap.org/pmwiki/pmwiki.php ).

Cheers,
Jason

All,



I've post this in VTK board but I didn't get the answer.  Before I set

out to implement it, I'll post it here.



I have a set of contours in axial orientation representing a ROI. I
need to sketch the ROI in coronal and sagittal plane, by connection the
points made from the intersection of the contours and the cutting plane.
Is there a function to do that in vtk or in ITK?



Some in VTK board suggested constructing a surface and create

the crosssection by cutting the surface.  But that is not what I need.

I need to do it in the rudimentary way for performance.

 Many thanks!

Xiaofeng
