手术模拟的准备阶段通常包括患者数据的分割，这是真实的视觉和触觉渲染所需要的。专家对3D患者数据集的分割可以持续几个小时到几天。在本文中，我们介绍了一种直接触觉体积绘制方法腰椎穿刺。用于分割的准备时间要短得多，并且与我们的参考系统相比，可以观察到针尖上几乎相同的力输出。专家需要完全分割的组织数量从腹部数据集的11个减少到3个，有300个切片。
The preparation phase for surgical simulations often comprises the segmentation of patient data, which is needed for realistic visual and haptic rendering. Expert segmentation of 3D patient data sets can last from several hours to days. In this paper we introduce a direct haptic volume rendering approach for lumbar punctures. Preparation time spent for segmentation is much shorter and compared to our reference system nearly identical force output at the needle tip can be observed. The number of structures to be completely segmented by an expert is reduced from 11 to 3 tissues in abdominal data sets with 300 slices.
