导航系统

The development of modern skin flap chirurgery needs badly the three- dimension picture system to display the blood supply and other profound structures and functions. This kind of system can also support the clinical training, designing of operative route, suppositional operation procedure and fidelity navigation during the operation. 3D imaging studies such as computed tomography and magnetic resonance provide the primary source of patient-specific data for such medical applications. The two-dimensional (2D) images produced by CT and MR imaging techniques represent a series of cross-sectional image slices through ones anatomy.

现代皮瓣外科学的发展迫切需要显示其血供等复杂结构和功能的三维图像系统，为临床医生的培训、手术入路的设计、手术过程的虚拟和术中的精确导航提供支持，同时随着人体标本来源的日趋减少，有必要建立一整套包括常用皮瓣、肌瓣和骨瓣在内的三维解剖以供骨科临床教学和训练所用，随着"虚拟人"、计算机虚拟技术和现代医学影像技术的快速发展，使得虚拟皮瓣外科手术的研究与应用成为可能。

Under the management corresponding of control system, the knowledge in knowledge base was used by inference machine to colligate the data and conditions in database, the models and methods in model method base were called to theorize and acquire adaptive navigation information.

在控制系统的管理协调下，推理机运用知识库中的知识，综合数据库的数据和条件，调用模型方法库中的模型和方法进行推理，获得适用的导航信息。

Error compensation is an efficient way to enhance the accuracy of navigation, but error calibration is the precondition of error compensation.

误差补偿是提高捷联惯导系统导航精度的有效途径，而误差标定则是误差补偿的前提。
