摘要： A C-arm imaging device method and system are provided with position determination means for determining the position of an imaging source (30) and an imaging apparatus (20), and means for determining a local gravity vector. The device and system may also be provided with a magnetic north sensor (58). Imaging source focal point displacement due to bending determination means and information storage means are also provided. The apparatus and system is used to determine a position of an imaging source (30), position of an imaging receptor (32), a local gravity vector and, if applicable, magnetic field distortion, for each of a plurality of orientations of the C-arm (22). Imaging source focal point displacement due to bending is determined using the position of the imaging source (30) and the position of the imaging detector (32) in correspondence to the local gravity vector and, if applicable, magnetic field distortion, for each of the plurality of orientations. This information can be stored for use in subsequent interpolation of imaging source focal point displacement based on a specific position of an imaging receptor (32) a specific local gravity vector. Such an apparatus and system facilitates a calibration process, and permits dispensing with one or more calibration plates.

摘要： A method is provided for maintaining a data set associated with an implant device intended for use during implant surgery on a selected patient. The method includes the steps of: storing pre-operative planning information in the data set configured for use during the implant surgery, the pre-operative planning information comprising image data representing the anatomy of the selected patient, a definition of the implant device based on an analysis of the anatomy represented in the image data such that the definition of the implant device includes one or more implant devices each having at least one different implant property, and surgical information including placement information of the implant device on the anatomy. The data set can then be amended to include intra-operative information including the actual implant device used during the implant surgery and details of the actual placement of the implant device used during the implant surgery. The amended data set is stored for subsequent access to facilitate outcome analysis (i.e. post-operative analysis) of the pre-operative planning information and the intra-operative information associated with the implant device.

摘要： A method and apparatus are disclosed for defining a three-dimensional coordinate system in relation to an anatomical structure (64) for use with computer-assisted surgical systems. At least three landmarks (66, 68, 70) associated with the anatomical structure (64) are identified. Landmarks are identified using a digitization device (96) and their location refined using at least one single calibrated X-ray image. Using the landmarks (66, 68, 70), first and second planes are defined, the second plane being orthogonal to the first plane. These planes define a coordinate system, which can be used to ascertain the position trajectory of any object (80) with respect to the anatomical structure. Exposure to imaging radiation and additional surgical procedure is minimized.

摘要： Device and method for planning a surgical operation by using virtual representation of a bone or a bone joint comprising reference bodies (13; 14) and pointers (7) having references (8) attached, a three-dimensional localizer device (6) comprising sensors (9) or transmitters, a digitizing device (18) and an image processing unit (10). By means of the references (8) and the three-dimensional localizer device (6) the position and the orientation of the reference bodies (13; 14) and the pointers (7) or the pointer tip (12) can be determined and represented at the display (19) of a computer (11). The image processing unit (10) permits the generation of a virtual three-dimensional surface at the display (19) containing the points that were previously determined by means of the pointers (7), the display of any desired and previously acquired relevant element (25) or combination of these elements from any desired angle of observation and the display of stationary or moving elements (25).
