摘要： A method comprises providing a current state image and at least one reference image, taken from a similar angle range. The image and the at least one reference image are superimposed and a visual representation visualizing the relation between the image and the reference image is provided in order to track displacements of the bone during subsequent operation steps. A system is provided which can use the image data to track displacements and determine deviation from a current state of the elements in question to a target state.

摘要： A method and a corresponding system are provided. The method comprises steps of providing 2D images and subsequently detecting outlines of a primary structure in each of the images. A visual representation of the 2D images is generated and the 2D images are then arranged as 2D slices in a 3D visual representation. To this end, at least two of the 2D images are taken at different imaging angles. The method provides a 3D visual representation of a region of interest comprising a primary structure to support a spatial sense of a user.

摘要： A computer assisted surgical system that includes an apparatus for imaging a region of interest of a portion of an anatomy of a subject; a memory containing executable instructions; and a processor programmed using the instructions to receive two or more two-dimensional images of the region of interest taken at different angles from the apparatus and process the two or more two-dimensional images to produce three dimensional information associated with the region of interest.

摘要： A device, a system and a method for determining an anteversion angle of a femoral shaft of a femur are provided. The device includes a provision unit and a processing unit. The provision unit is configured to provide image data of the femur, and wherein the processing unit is configured to determine a longitudinal shaft axis extending through the femoral shaft based on the image data. The processing unit is further configured to determine at least two landmarks of the femur based on the image data, and place a tangent trough each landmark parallel to the shaft axis. The processing unit is configured to determine the anteversion angle of the femoral shaft based on the tangents and the shaft axis of the femoral shaft.

摘要： A method of treating a bone fracture includes taking a first 2D image of an implant and a reference body with an imaging device; creating a 3D orientation of the reference body and the implant based on the 2D image; determining an actual axis of delivery of a bone screw through an opening extending through the implant; determining an optimal axis of delivery of the bone screw through the opening such that the optimal axis of delivery guides the bone screw toward a medically optimal location; and moving the implant such that the optimal axis of delivery and the actual axis of delivery coincide.

摘要： A computer program element and a device are provided for processing a 2D projection image generated during a procedure of fracture treatment of a bone. The computer program element comprises sets of instructions for detecting the reference body in the 2D projection image, detecting at least one element out of the group consisting of an instrument, an implant and an anatomical structure in the 2D projection image, and identifying a current state of the element, determining a state of progress of the procedure of fracture treatment, and providing information regarding steps to be performed next.
