Feature-based texture display for detection of polyps on flattened colon volume

This paper presents a volume-based algorithm to flatten the colon. Based on the flattened colon volume, three different display schemes are adapted to transfer the three-different imensional (3D) flattened colon volume into a 2D image. One display scheme is surface-based rendering, one is volume-based rendering, and the third one is feature-based texture display. These three displays generate not only a traditional flattened-colon surface image, but also a feature-based texture image which can be utilized to characterize and detect the colonic polyps, resulting in a new way to visualize the entire colon.
