Abstract:
A system for use during a procedure on a body, said system generating a display representing a position of two or more body elements during the procedure, said system comprising:a memory storing an image data set representing the position of the two or more body elements based on scans taken of the body prior to the procedure, the image data set having a plurality of data points and corresponding to a plurality of reference points for each of the body elements, the reference points of a particular body element having a known spatial relation to the data points of the particular body element; means for identifying, during the procedure, the position of the reference points of each of the body elements relative to the reference points of the other body elements; a processor modifying the spatial relation of the data points of one body element relative to the data points of another body element according to the identified relative position of the reference points during the procedure as identified by the identifying means, said processor generating a displaced image data set representing the position of the body elements during the procedure; and a display utilizing the displaced image data set generated by the processor, illustrating the relative position of the body elements during the procedure.
