Hi Vikram,
reconstructing 3D vessels from biplane or monoplane angiography is a task that
vmtk is not built for, you necessarily have to dive into ITK and do some
groundwork to make it happen. In general, it's a problem there is no general
solution for, as it requires some prior knowledge on what is the expected shape
of the objects you are reconstructing, how many projections you have, what's
the geometry of your system. However, I encourage you to send a message to the
Slicer mailing list, they may have more concrete suggestions.
As to OCT images, if vmtk can't read them it's likely that Slicer can't read
them either, because they're based on very similar I/O mechanisms. It might be
that the cat format is some form of raw format, but you need to know more about
the format specification, you should probably ask for details from the OCT
support.
Best regards
Luca
