摘要： A method verifying the position of a surgically inserted orthopedic insert. A preoperative three dimensional image data set of the surgical site is generated, showing the bone into which the insert is to be inserted. During the insertion procedure, a series of intraoperative two-dimensional fluoroscope images are generated, each at a known pose relative to the bone, showing the insert during or after insertion into the bone. The 3-D position of the insert is determined in an intraoperative three dimensional image data set reconstructed from the series of intraoperative 2-D fluoroscope images. The reconstructed intraoperative 3-D image data set is registered with the preoperative three dimensional image data set, such as by comparison of imaged anatomical features. Once this registration is achieved, the determined 3-D position of the insert is used to implant a virtual image of the insert into the preoperative three dimensional image data set.
