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。

While improving people's production, collecting, organizing, transmitting and using information way of knowledge, it is a mechanism of information service too, Structure and service have changed enormously, how to combine some advanced information technologies in the management and service applied to the library, Promote the routine with the technology , change the library and understand the traditional mode, devoted to building and regarding navigating in knowledge as the development environment which serves the idea , no longer only confine to offering documents in storage to readers, Offer usable documents on all networks, help teaching and scientific research to be meanings in which this subject explores.

There was no radiancy in the MRI-guided percutaneous targeting intervention and cryoablation for tumor and the greatest advantage was to show the size,configuration and location of iceball exactly.Also it could estimate treatment effect accurately.

而冷冻消融治疗是微创介入技术之一，冷冻消融治疗多在CT或B超引导下进行，而开放磁共振导航下经皮穿刺冷冻消融治疗肝肿瘤技术，除无辐射性外，其最大优势在于术中对冰球大小、形态、位置的准确显示；能准确评价治疗效果。

Bayesian theory provides a good framework for integrating prior knowledge and maximum likelihood estimation. Bayesian based particle filtering technology has been proven to be successful for non-linear and non-Gaussian estimation problems and effective for solving tracking problems. Within methods of this class, tracking is modeled by a state-space time series estimation problem, which is solved using a sequential Monte Carlo estimation method.
