1. An image data registration system comprising:

  • an image data storage unit for storing a first data set of three-dimensional image data associated with a predetermined portion of an anatomical body with reference to a first coordinate frame;

    an image data acquisition and storage device for obtaining and storing a second data set of three-dimensional image data associated with a surface of said predetermined portion of said object with reference to a second coordinate frame, said image data acquisition and storage device comprises a surface sensing unit for sensing the outer skin surface of said predetermined portion of the body so as to obtain said second data set of three-dimensional image data; and

    an image data processor for registering said first and second data sets to generate a matched image data set in which said first coordinate frame is relatively aligned with said second coordinate frame.
