<P>PROBLEM TO BE SOLVED: To provide a medical navigation system and method for representing/extracting a medical instrument (tool) and/or an implant (embedded object) in a fluoroscopic image. <P>SOLUTION: The system includes a processor 870 configured to establish a surface boundary for a region of interest depicted in the image and configured to determine a position of the tool or implant 850 with respect to the surface boundary, and a display 880 configured to dynamically display the image and the representation to a user. The processor generates a representation of the tool or implant based on the position with respect to the surface boundary. A portion of the tool or implant inside the surface boundary is depicted in the representation with a degree of transparency compared to a portion of the tool or implant outside the surface boundary. <P>COPYRIGHT: (C)2008,JPO&INPIT |
