Advanced volume visualization for interactive extraction and physics-based modeling of volume data

This paper proposes an advanced volume representation of 3D geometries and presents its application for volume visualization of medical images. 3D geometry is represented using cross sections of grids and visualized volumetrically using a slice-based volume rendering method. The developed framework achieves real-time visualization on general purpose PCs and graphic hardware. As practical application of the framework, on-demand extraction on 3D reconstructed images and volumetric representation in physics-based simulation like deformation and cutting are introduced. Performance and effectiveness of the proposed methods are confirmed in preliminary use.
