In one form of the present invention, there is provided an apparatus for producing a virtual road map of a patient's vascular anatomy for use by a surgeon while conducting a procedure on the patient's vascular anatomy, the apparatus comprising: a virtual 3D model of the patient's anatomy, wherein the virtual 3D model comprises a virtual 3D structure representing bony structure of the patient and a virtual 3D structure representing vascular structure of the patient, with the virtual 3D structure representing bony structure of the patient being in proper registration with the virtual 3D structure representing vascular structure of the patient; a fluoroscope for providing real-time images of the bony structure of the patient and a surgical device being used in the procedure; registration apparatus for placing the virtual 3D model in proper registration with the patient space of the fluoroscope; bone mask substraction apparatus for (i) generation a bone mask of the bony structure of the patient, and (ii) substracting the same from the real-time images provided by the fluoroscope, whereby to create modified fluoroscope images omitting bony structure; and image generating apparatus for generating the virtual road map, wherein the virtual road map comprises a composite image combining (i) images of the virtual 3D structure representing vascular structure of the patient, and (ii) modified fluoroscope images omitting bony structure, wherein the images of the virtual 3D structure representing vascular structure of the patient are in proper registration with the modified fluoroscope images omitting bony structure. |
