  • Patent number: 12159421
    Abstract: A method of finding a set of corresponding points in images to be registered. According to the method, an input unit of the system receives a first user input, indicative of a reference point in an intraoperative image. A processing unit sets a reference area surrounding the reference point and converts the image data points in the reference area to a intraoperative point cloud. The input unit receives a second user input, indicative of a candidate point in a preoperative image. The processing unit sets a search area surrounding the reference point and converts the image data points in the reference area to a preoperative point cloud. By comparing geometric feature descriptors of the image data points, the processing unit finds a target point in the preoperative image corresponding to the reference point and defines the points as set of corresponding points.

  • Publication number: 20230113384
    Abstract: A method of estimating a partial deformation of an organ in which point clouds are calculated from intraoperative image data captured before and after a partial deformation motion of an organ. Geometric feature vectors are assigned to unmoving points, whose position does not change due to the partial deformation motion. Difference vectors indicating the change of the geometric feature vectors due to a change of position of moving in proximity to the unmoving points are utilized to estimate the partial deformation motion of the organ.
