[Insight-users] Advice on preprocessing before surface rendering

Hi,

I have images of the MR angiography of brain, for which I would like to do 
surface rendering of the vessels. The problem is that there is a high 
intensity noise in the lower and central part of the images, which reduces 
the quality of the rendering. Could anybody recommend me some preprocessing 
steps to enhance/segment/something  the vessels before the surface rendering. 
To demonstrate the "quality" of the images I uploaded the montage of 4/180 
slices on web:

Thanks a lot for advice.

Martin
