VolGraph―A PC-Based Visualization System for Three-Dimensional Medical Reconstructions

摘要

Three-dimensional reconstructions from tomography slices are paid great attention in medical applications nowadays. This paper introduces the design and the implement of VolGraph system; a new, inexpensive, PC-based visualization tool for three-dimensional medical reconstructions, which fully integrates the latest popular visualization algorithms ranging from classical surface rendering algorithm (Marching Cubes) to volume rendering algorithms, such as Ray Casting, Splatting, and Shear - Warp. The input of VolGraph can be medical images including CT, MRI, etc, and the output can be in common image, VRMI/XML or animation formats. Practice proves that the realization of a medical volume visualization system is now feasible on desktop PCs.
