Surgical navigation systems are becoming eommon, which realize realtime (or rapid) 3D recbnstmction of the operating room and internal anatomical structures of the patient. In this work, we focus on the problems of dealing with deformation of soft tissues in surgical nayigation.As basic technologies for this ptrpose, we have developed techniques for deformation detection during surgery, 3D ultrasound image acquisition, and segmentation and registration of soft tissue region extraction and shape correction. We emphasized that we have aimed at a special application purppse, that is, application to soft tissue surgery, while the obtained results can be regarded as general purpose methods for 3D image analysis and spatial integration. For example, a rapid method for magnetic tracker calibration can be regarded as a useful tool for wide ranges of virtual/autmented/mixed reality systems using magnetic trackers although it was originally developed for 3D laparoscopic ultrasound systems was developed to deal with surgical environments. Another example is a nonrigid registration method which deals with tissue slide of soft tissue organs. The developed method is particularly useful for temporal registration of dynamic CT image of the liver while it gives deep insights to dealing with discontinuities of deformation vector field involved in many computer vision problems. As a result, we attain the develop ment of technologies suitable for ithe operating room and internal anatomical structures of soft tissues as well as useful and interesting in wider contexts of image analysis and spatial data analysis.

手术导航系统是实现手术室和患者体内解剖结构实时（或快速）三维重建的常用系统。本文针对外科手术中软组织形变的处理问题，研究了手术过程中的形变检测技术、三维超声图像采集技术、软组织区域提取的分割与配准技术以及形状校正技术。我们强调，我们针对的是一个特殊的应用purppse，即应用于软组织手术，而所获得的结果可以被视为三维图像分析和空间整合的通用方法。例如，用于磁跟踪器校准的快速方法可以被认为是使用磁跟踪器的各种虚拟/自动/混合现实系统的有用工具，尽管它最初是为3D腹腔镜超声系统开发的，是为了处理手术环境。另一示例是处理软组织器官的组织载玻片的非刚性配准方法。所开发的方法是特别有用的肝脏的动态CT图像的时间配准，同时它提供了深刻的见解，以处理涉及许多计算机视觉问题的变形矢量场的不连续性。因此，我们实现了适用于手术室和软组织内部解剖结构的技术的发展，以及在更广泛的图像分析和空间数据分析背景下的有用和有趣。
