Claim One:
1. A surgical navigation system ( 60 ) for integrating a plurality of images of an anatomical region of a body including a pre-operative scan image ( 31 ), an intra-operative fluoroscopic image ( 42 ) and an intra-operative endoscopic image ( 23 ), the surgical navigation system ( 60 ) comprising: an image integrator ( 61 ) operable to generate an integrated image matrix (T X-E ) including an integration of a fluoroscopic image matrix (T X-CT ) and an endoscopic image matrix (T CT-E ), wherein the fluoroscopic image matrix (T X-CT ) includes a transformation between the intra-operative fluoroscopic image ( 42 ) and the pre-operative scan image ( 31 ), and wherein the endoscopic image matrix (T CT-E ) includes a transformation between the pre-operative scan image ( 31 ) and the intra-operative endoscopic image ( 23 ); and a tool tracker ( 62 ) operable to generate an integrated tracking matrix (T T-X ) and a scan tracking matrix (T T-CT ), wherein the integrated tracking matrix (T T-X ) includes an integration of the integrated image matrix (T X-E ) and an endoscopic tracking matrix (T T-E ), wherein the scan tracking matrix (T T-CT ) includes an integration of the endoscopic image matrix (T CT-E ) and the endoscopic tracking matrix (T T-E ), and wherein the endoscopic tracking matrix (T T-E ) represents a tracking of a surgical tool ( 21 ) within the intra-operative endoscopic image ( 23 ).
