• 論文の詳細を見る

• This paper presents an efficient graphics hardware-based method to segment and visualize level-set surfaces as interactive rates. Our method is composed of memory manager, level-set solver, and volume Tenderer. The memory manager which performs in CPU generates page table, inverse page table and available page stack as well as process the activation and inactivation of pages. The level-set solver computes only voxels near the iso-surface. To run efficiently on GPUs, volume is decomposed into a set of small pages. The volume Tenderer performs volume rendering of the original data simultaneously with the evolving level set in GPU. Experimental results using two chest CT datasets show that our graphics hardware-based level-set method is much faster than software-based one.
