1. A system for identifying a location of a physical structure in a body, comprising:

  • an electronic control unit configured to;

    register a first echocardiography image of a portion of said body in a three-dimensional coordinate system responsive to a position of a fiducial marker in said first image and a position of a first sensor in said three-dimensional coordinate system, said sensor associated with said fiducial marker;

    identify said location of said physical structure in said three-dimensional coordinate system responsive to flow of a fluid shown in said image; and

    add points corresponding to said location of said physical structure to a point cloud corresponding to said physical environment, said point cloud comprising points collected with said sensor.
