Detecting changes in position of an implant in a patient, involves distributing markers on salient points of implant through two-dimensional X-ray imaging, and constructing three-dimensional image of implant based on distributed markers

摘要

The method involves distributing markers on salient points of an implant through two-dimensional X-ray imaging, calculating the feasibility proportion of the implant based on the marker distribution, and constructing a three-dimensional image of the implant based on the distributed markers. The markers are arranged surrounding the implant. An independent claim is included for the X-ray apparatus used in detecting changes in position of an implant.
