thanks for the suggestion. 

i have tried with vol3d from the fileexchange. previously i
used to use isosurface command directly with the 3d matrix
that i have generated. with the vol3d it look better than that. 

i will look for HD Volume Rendering. 

I have the following queries. 

I have a 3D matrix of the CT images. Is it possible to
reconstruct them to 2D images at any other angle other than
sagital, coronal. ie., other than horizontal and vertical. 

Basically i am trying to reconstruct the colon from the CT
image. I have segmented the colon from the CT image and
constructed a 3D matrix. The colon is folded in our body.
So, when seen(reconstructed parallel to the body) from the
front of the body, the folded colon can be viewed. At this
angle it  will be clear to see the colon. 

The image will have to be reconstructed perpendicular to the
surface of the colon. Since the colon is folded, it is
neccessary to reconstruct them at oblique angles. Is it
possible?

If the surface/volume rendering result were good, i thought
of using the campos and camva of the matlab to navigate
(user guided) through the colon, by manually getting the
camera position from the user. But the images that i have is
not great, so the 3D is not that good to navigate. So i
thought if i could view the colon as 2D at particular angle
and reconstruct them.

thanks
