1. A spatial registration apparatus, comprising:

  • a medical instrument or sensor probe;

    a camera rigidly connected with the medical instrument or sensor probe;

    a fiducial marker affixed to an object of interest, the object of interest being different from the medical instrument or sensor probe and different from the camera;

    at least one first processor operatively coupled with a first memory, the first memory having first instructions for execution by the at least one first processor, wherein the first memory stores a relative location and orientation between the medical instrument or sensor probe and the rigidly connected camera, wherein the first instructions, when executed by the at least one first processor, cause the at least one first processor to determine a pose of the camera with respect to the fiducial marker using an image of the fiducial marker captured by the camera and then transform the pose, using the stored relative location and orientation between the medical instrument or sensor probe and the rigidly connected camera, to determine a first spatial position and orientation of the medical instrument or sensor probe with respect to the fiducial marker, the at least one first processor associating a first scan of the object of interest from the medical instrument or sensor probe with the first spatial position and orientation of the medical instrument or sensor probe to create a first spatially registered scan, the first scan being time synchronized with the first spatial position and orientation of the medical instrument or sensor probe;

    a network; and

    at least one second processor operatively coupled with a second memory, the second memory having second instructions for execution by the at least one second processor, the second instructions, when executed by the at least one second processor, cause the at least one second processor to derive visualization data from the first spatially registered scan from the medical instrument or sensor probe using the first spatial position and orientation of the medical instrument or sensor probe with respect to the fiducial marker, and display the visualization data, on a first display, to a first user.
