Dicom-RT structure imports

Are there any scripts out there for opening/importing Dicom-RT structure
files and parsing the structure information within them?

What I'm looking to do is create binary masks of the structures so that I
can apply them to a 3D x-ray dose matrix to extract information on dose to
each specific structure.

I can do a dicomread() bu the information in there seems a bit
gobbledegook - are there any scripts already out there for doign this so
that I don't have to reinvent the wheel?

Cheers,

The gobbledygook is the uninterpreted RT data for masks, contours, etc.,
but I haven't seen any MATLAB code to parse it. I tried doing a little
bit of this myself a while back, but I got pulled elsewhere and never
got back to it.

The portion of the DICOM standard that covers RT is actually fairly well
contained. If you want to interpret the RT-specific values, start with
sections A.17.3, A.18.3, and A.19.3 of part 3 of the standard:
<medical.nema.org>. The tables will give you pointers to the specific
sections that explain how to interpret values.

I would also like to read 3D scans that come in dicom-rt format.
is there any file that can do it?

thanks for letting me know.
