Hi Jan,

   To automatically calculate the path of the camera is a  difficult
problem.
However, check out this paper from Stanford University:
Automated flight path planning for virtual endoscopy, Paik, Beaulieu,
Jeffrey et al,
Medical Physics 25(5), May 1998, p. 629. They find the medial axis transform

by iterative thinning of the segmented structure. It was applied to virtual
colonoscopy,
one aorta and a bronchial tree
