Within the limits of current technology, many applications of a virtual environment will trade-off accuracy for speed. This is not an acceptable compromise in a medical training application where both are essential. Efficient algorithms must therefore be developed. The purpose of this project is the development and validation of a novel physics-based real time tool manipulation model, which is easy to integrate into any medical virtual environment that requires support for the insertion of long flexible tools into complex geometries. This encompasses medical specialities such as vascular interventional radiology, endoscopy, and laparoscopy, where training, prototyping of new instruments/tools and mission rehearsal can all be facilitated by using an immersive medical virtual environment. Our model recognises and uses accurately patient specific data and adapts to the geometrical complexity of the vessel in real time.
在当前技术的限制范围内，虚拟环境的许多应用将在准确性和速度之间进行权衡。在医学训练应用中，准确性和速度都至关重要，这种权衡是不可接受的。因此，必须开发高效的算法。本项目的目的是开发并验证一种基于物理的新型实时工具操作模型，该模型易于集成到任何需要支持将长柔性工具插入复杂几何形状的医学虚拟环境中。这涵盖了血管介入放射学、内窥镜检查和腹腔镜检查等医学专业领域，在这些领域中，使用沉浸式医学虚拟环境可以促进训练、新器械/工具的原型制作以及任务演练。我们的模型能够准确识别并使用患者的特定数据，并实时适应血管的几何复杂性。
