Abstract: A surgical system including a surgical instrument having a shaft, an image sensor positioned at a distal end of the shaft, the image sensor being configured to capture images of a target object of a living object, and a control grip is arranged at a proximal end of the shaft. The surgical system further including a monitor for displaying the images and a controller configured to display a virtual target object model image of the target object on the monitor. Where the control grip is configured to position the virtual target object model image displayed on the monitor at a determined position and rotate the virtual target object model image displayed on the monitor at the determined position.

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.

Abstract: A method for operating a medical navigation system for an image-guided surgical procedure including: training a first artificial neural network on a set of surgical image video data of a target object of a patient representing a video image, and identifying the structure of the target object; training a second artificial neural network on at least one virtual three-dimensional target object model of the target object and identifying the structure of the virtual three-dimensional target object model by the identified structure of the target object; training a third artificial neural network by the identified structure of the target object and the structure of the virtual three-dimensional target object model and aligning the identified structure of the target object, with the structure of the corresponding target object of the virtual three-dimensional target object model, which is identified by the second artificial neural network.

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.

Abstract: A medical support apparatus has one processor or more, and the processor is configured to: acquire a medical image; and based on the medical image, generate a guidance display that indicates a boundary between segments whose recommendation levels for medical treatment are different in the medical image and that is to be superimposed on the medical image.
