ABSTRACT:
Methods for determining a position of an implant in an ultrasound imaging system are provided. In one embodiment, the method includes determining an initial transformation matrix based at least in part on positions of a plurality of implants in a fluoroscopy coordinate system and estimated positions of said plurality of implants in an ultrasound coordinate system, modifying said initial transformation matrix based on an accuracy of said estimated positions of said plurality of implants, and determining a position of an implant in said ultrasound coordinate system based at least in part on said modified transformation. Computer program product, systems, and user interfaces associated with embodiments of the methods are also provided.
