ABSTRACT
Acquiring image data of bone biopsies by a micro-CT
scanner is today a common technique. The amount of
data to be assessed is huge. The task to assess quantitative
measures requires a concise visualization. We present vi-
sualization techniques that can be used interactively on
state-of-the-art PCs and demonstrate how the frontier can
be pushed further. A skeletonization process is applied to
the image of the bone to create the central surface. Af-
ter triangulation this surface can be renderd at interac-
tive frame rates. When the surface is additionally colored
by local measures (mean grey value of image data, local
thickness) the overall structure and details can be recog-
nized at the same time. This can facilitate the exploration
of the biopsy and can help finding special features.
