本文提出了一套新的技术，外科医生可以交互式地操纵病人特定的体积模型共享手术过程。为了处理手术工具和器官之间的物理交互，我们提出了一个简单的基于表面约束的操作算法，以始终模拟常见的手术操作，如抓取，保持和缩回。我们的计算模型是能够模拟软组织变形和切割在真实的时间。我们还提出了可视化技术，以快速可视化的变形图像上的时变，体积信息。本文展示了成功的方法，使模拟手术过程中，这种模拟有利于术前规划和排练的方式。
This paper presents a new set of techniques by which surgeons can interactively manipulate patient-specific volumetric models for sharing surgical process. To handle physical interaction between the surgical tools and organs, we propose a simple surface-constraint-based manipulation algorithm to consistently simulate common surgical manipulations such as grasping, holding and retraction. Our computation model is capable of simulating soft-tissue deformation and incision in real time. We also present visualization techniques in order to rapidly visualize time-varying, volumetric information on the deformed image. This paper demonstrates the success of the proposed methods in enabling the simulation of surgical processes, and the ways in which this simulation facilitates preoperative planning and rehearsal.
