Three-Dimensional Analysis by the Cone-Beam Type CT of the Nasal Region of an Orang-utan

Abstract

We used the cone-beam type CT (Computed Tomography) scanning to study the nasal region of the orang-utan carcass head. The cone-beam type CT is the simplest and the most reasonable way to obtain 3 D data from the dead bodies of animals. In the orang-utan head, the complicated structure of the nasal conchae and the laterally-enlarged maxillary sinus were observable in a non-destructive 3 D imaging analysis. These findings will be effective in morphologically detailing the olfactory function of this species in the future.
