    • A method of navigating a cavity of a subject employing images from a previous navigation is provided. In a first endoscopic examination, a set of schemas and at least one bookmark are saved in a data storage device. Each schema includes at least a still image in a cavity and a direction of a distal end. At least one bookmark is defined as at least one schema at a point of interest. In a second endoscopic examination, still images during navigation of an endoscope are compared with still images in the set of schemas to find a match, and use the information derived from the match to determine the location and the orientation of the distal end. An endoscopic system for effecting this method and a non-transitory machine-readable storage medium embodying a program for operating such an endoscopic system are also provided.
    • 提供了一种使用来自先前导航的图像来导航对象的空腔的方法。 在第一内窥镜检查中,将一组方案和至少一个书签保存在数据存储设备中。 每个模式至少包括空腔中的静止图像和远端的方向。 至少有一个书签被定义为至少一个兴趣点的模式。 在第二次内窥镜检查中,将内窥镜导航期间的静止图像与该组图像中的静止图像进行比较以找到匹配,并使用从匹配导出的信息来确定远端的位置和方向。 还提供了用于实现该方法的内窥镜系统和体现用于操作这种内窥镜系统的程序的非暂时性机器可读存储介质。
