Alternatively, the tracking element can be housed in a separate module that can be coupled to either the reamer or impactor. The tracking element will couple to a predetermined location. Points in 3D space can be registered to provide a frame of reference for the tracking element or when the tracking element is moved from tool to tool. The tracking element sends data from the reamer or impactor wirelessly. The remote system receives the tracking data and can further process the data. A display on the remote system can support placement and orientation of the tool to aid in the installation of the prosthetic component.

  • Patent number: 9261596
    Abstract: A method for ultrasound imaging of anatomical tissue. A first signal is received from a first imaging ultrasound wave which has been reflected from a location in the anatomical tissue during a first time period. A second signal is received from a second imaging ultrasound wave which has been reflected from the location in the anatomical tissue during a later second time period, following a discrete medical treatment. The second signal is subtracted from the first signal to form a difference signal. The difference signal may be scaled, spatially filtered, then used to generate an indication, the indication showing the effect of the medical treatment in the location in the anatomical tissue.
