First Claim
1. A system for use during a medical or surgical procedure on a portion of a body, said system for use with a discriminated image data set identifying skeletal elements of the portion of the body and representing a position and a geometry of the skeletal elements of the portion of the body;
- said system comprising;
a memory for storing the discriminated image data set;
an imaging device for producing, during the procedure, a density image of the portion of the body;
a processor modifying the discriminated image data set stored in the memory according to the density image, said processor generating a displaced image data set representing the position and geometry of the skeletal elements of the portion of the body during the procedure; and
a display utilizing the displaced image data set illustrating the position and geometry of the skeletal elements of the portion of the body during the procedure.

Abstract
A system for use during a medical or surgical procedure on a body. The system modifies a reference image data set according to a density image of a body element during a procedure, generates a displaced image data set representing the position and geometry of the body element during the procedure, and compares the density image of the body element during the procedure to the reference image of the body element. The system also includes a display utilizing the displaced image data set generated by the processor to illustrate the position and geometry of the body element during the procedure. Methods relating to the system are also disclosed.

17. A system for displaying relative positions of first and second body portions during a procedure on a body, the system for use with a discriminated image data subset representing a position and geometry of the first and second body portions;
- said image data subset defining a position and geometry of the first and second body portions, the image data subset further having a plurality of data points correlatable to a plurality of reference points for the first and second body portions, the position of reference points of a particular body portion relative to the data points for that particular body portion being known;
said system comprising;a memory for storing the discriminated image subdata set; a reference system determining, during the procedure, the position of the reference points of the first body portion of the discriminated image data subset relative to the reference points of the second body portion of the discriminated image data subset; a radiographic device producing a two-dimensional radiographic image of the first and second body portions during the procedure which includes the identification of reference points of the first and second body portions; wherein the processor further digitizes the radiographic image and generates a displaced image data set representing the position of the first and second body portions during the procedure by modifying the image data subset stored in the memory using an iterative process such that a two-dimensional projection through the displaced image data set substantially matches the radiographic image; and a display utilizing the displaced image data set to display the relative position of the first and second body portions during the procedure. - View Dependent Claims (18, 19, 20, 21, 26)
- said image data subset defining a position and geometry of the first and second body portions, the image data subset further having a plurality of data points correlatable to a plurality of reference points for the first and second body portions, the position of reference points of a particular body portion relative to the data points for that particular body portion being known;
- 22. The system of 17, wherein the radiographic device is a fluoroscopic device comprising a fluoroscopic tube and a fluoroscopic plate so that the first and second body portions may be positioned therebetween during the procedure.

27. A method for use during a procedure, said method for use with a discriminated image data set identifying one or more body portions and representing a position and a geometry of the one or more body portions, the method comprising:
-
storing the discriminated image data set in a memory; producing a two-dimensional image based on density of the one or more body portions during the procedure; producing a displaced image data set by modifying the discriminated image data set stored in the memory such that a two-dimensional projection through the displaced image data set matches the two-dimensional image during the procedure; and generating a display based on the displaced image data set illustrating the position of the one or more body portions during the procedure. - View Dependent Claims (28, 29, 30, 31)
