CT colonography is an emerging technique for colorectal
cancer screening. This technique facilitates noninvasive
imaging of the colon interior by generating virtual
reality models of the colon lumen. Manual navigation
through these models is a slow and tedious process.
It is possible to automate navigation by calculating the centreline
of the colon lumen. There are numerous well documented
approaches for centreline calculation. Many of
these techniques have been developed as alternatives to 3D
topological thinning which has been discounted by others
due to its computationally intensive nature. This paper describes
a fully automated, optimised version of 3D topological
thinning that has been specifically developed for calculating
the centreline of the human colon.
