A Novel Visualization Technique for Virtual Colonoscopy Using One-Sided Transparency

This paper proposes a new visualization technique for tubular shape visualization called one-sided transparency (OST). The technique effectively removes the exterior face of a surface, making it transparent, while keeping the interior opaque for viewing. OST is particularly useful in virtual colonoscopy, giving superior visibility coverage with reduced data memory requirements compared to state-of-the-art techniques. The technique achieved surface visibility coverage of up to \( 99.5 \pm 0.2\,\% \) when applied on 5 clinical sets using a fly-over (FO) approach. OST also lends improvements to other VC approaches that depend on centerline extraction of the colon volume.
