摘要: 从医学体数据中得到对象的三维可视图像有广泛的应用领域,例如医学诊断、法医学、古人类学等.本文讨论并分析了一种基于表面再现的 Marching cubes算法的优点及存在的不足,给出了算法在时空开销、不确定性等方面的改进和解决方案,改进后的算法在实际系统中取得了良好的效果.

Abstract: Three-dimensional imaging of medical objects from volume data is considered increasingly useful in various fields, such as medical diagnosis, forensic medicine, palaeoanthropology etc.Marching Cubes algorithm, as one of the advanced surface-based rendering algorithms,is analyzed.The algorithm is improved in several aspects, including solution in several ambiguous cases and shortage of memory, reduction of the computing cost.An advanced 3D medical volume data rendering prototype system is provided, which is based on SGI Indigo2 Open GL platform and consists of a powerful display engine and has satisfying solution.
