计算机辅助手术的一项基本任务是术前图像数据与手术室坐标系的配准。这可以通过使用术中成像和登记术前和术中数据集来实现。对于术中成像，超声是一种强大的工具，因为它缺乏电离辐射，因为它快速、廉价和容易获取数据。我们提出了一种骨表面与超声体积数据配准的表面体积匹配算法。考虑到超声只显示部分骨表面，骨表面是根据术前CT数据估计的。该方法得到了可靠的匹配结果。它们与腰椎资料一起显示。
An essential task of computer assisted surgery is the registration of preoperative image data with the coordinate system of the operating room. This can be reached by using intraoperative imaging and registrating preoperative and intraoperative datasets. For intraoperative imaging ultrasound is a powerful tool due to the lack of ionizing radiation and because of its fast, inexpensive and easy data acquisition. We propose a surface volume matching algorithm for the registration of bone surfaces and ultrasound volume data. The bone surface is estimated from the preoperative CT data by taking into account that ultrasound only shows parts of the bone surface. By our method reliable matching results are obtained. They are shown with data of the lumbar spine.
