The University of Pennsylvania has established the following five objectives for this project: 1. Scaling deformable models of various major organs in the chest or abnormal cavity, where the scaling represents normal, diseased, or hypertrophied situations. 2. Allowing the scaled organs to move and re-arrange themselves into anatomically and physically realistic positions. 3. Mapping Visible Human datasets (or currently available imaging datasets) onto the deformation models to impart fine-grained structure and surgically-relevant anatomy, such as major arteries, nerves and support tissues. 4. Building a qualitative model of microscopic organ function correlated with spatial properties that represents, inter alia, notions of container, conduit, obstruction, leakage, distention, collapse, etc. 5. Using the qualitative functional model and the physical/spatial model to model candidate surgical procedures appropriate to training and experimentation in virtual simulated environments.

宾夕法尼亚大学建立了以下五个 本项目的目标： 1.胸部各种主要器官的缩放可变形模型 或异常腔，其中缩放代表正常，患病， 或肥大的情况下。 2.允许缩放的器官移动和重新排列自己 在解剖学和物理学上真实的位置。 3.映射可视人体数据集（或当前可用的成像 数据集）上的变形模型，以赋予细粒度的 结构和解剖学相关解剖结构，如主动脉， 神经和支持组织。 4.建立微观器官功能的定性模型 与空间特性相关，阿利亚是， 容器、导管、阻塞、泄漏、膨胀的概念， 倒塌等。 5.使用定性功能模型和物理/空间 模型到模型候选外科手术适合于 在虚拟模拟环境中进行培训和实验。
