Abstract :
In this work we show a technique based on Shell Rendering to process a volume composed by a set of tomographic images in such a way that it can be rotated and re-sliced in a new volume in an appropriate angle. We also propose two different techniques for dealing with quality of rendered images. In the last case, the quality of the new images is comparable to the original ones.
