Abstract

The present invention provides a method, including: obtaining a first image from a first imaging modality; identifying on the first image from the first imaging modality obtaining a second image from a second imaging modality; generating a compatible virtual image from the first image from the first imaging modality; mapping planning data on the compatible virtual image; coarse registering of the second image from the second imaging modality to the first image from the first imaging modality; identifying at least one element of the mapped planning data from the compatible virtual image; identifying at least one corresponding element on the second imaging modality; mapping the at least one corresponding element on the second imaging modality; fine registering of the second image from the second imaging modality to the first image from the first imaging modality; generating a third image.

What is claimed is: 
     
         1 . A method, comprising:
 obtaining a first image from a first imaging modality;   identifying on the first image from the first imaging modality at least one element, wherein the at least one element comprises a landmark, an area of interest, an incision point, a bifurcation, an organ, or any combination thereof,   obtaining a second image from a second imaging modality;   generating a compatible virtual image from the first image from the first imaging modality;   mapping planning data on the compatible virtual image;
 wherein mapped planning data corresponds to the at least one element, 
   coarse registering of the second image from the second imaging modality to the first image from the first imaging modality;   identifying at least one element of the mapped planning data from the compatible virtual image;   identifying at least one corresponding element on the second imaging modality;   mapping the at least one corresponding element on the second imaging modality;   fine registering of the second image from the second imaging modality to the first image from the first imaging modality;   generating a third image;
 wherein the third image is an augmented image including a highlighted area of interest. 
   
     
     
         2 . The method of  claim 1 , further comprising superimposing the at least one image, a portion of the at least one image, or a planning information derived from the first imaging modality over the second imaging modality. 
     
     
         3 . The method of  claim 1 , further comprising using at least one instruction, where the at least one instruction can include information regarding navigation, guidance, or a combination thereof. 
     
     
         4 . The method of  claim 3 , wherein the guidance includes information regarding a positioning of a device shown the second imaging modality, wherein the device comprises a fluoroscopic C-Arm, as to result in achieving visibility for the area of interest, incision points, anatomical structures, or tool access direction. 
     
     
         5 . The method of  claim 1 , further comprising tracking of at least one anatomical structure by use of at least one subsequent image derived from the second imaging modality, wherein the second imaging modality comprises a fluoroscopic video configured to have substantially the same acquisition parameters, and wherein the acquisition parameters comprise mode, position, field of view, or any combination thereof, to generate the augmented fluoroscopic image by suppressing static anatomic structures and/or improving signal to noise of underlying soft tissue. 
     
     
         6 . The method of  claim 1 , further comprising performing a multiphase registration,
 wherein the at least one substantially static object is first registered; and   wherein at least one dynamic object is second registered,
 wherein the at least one dynamic object comprises a diaphragm, a bronchus, a blood vessel, or any combination thereof. 
   
     
     
         7 . The method of  claim 1 , further comprising deemphasizing at least one interfering structure. 
     
     
         8 . The method of  claim 2 , wherein the compatible virtual image is not generated while the planning data from first imaging modality is transferred to second imaging modality by means of image registration. 
     
     
         9 . A method comprising:
 using at least two intraoperative images with known relative movement and rotation to generate a grouping of pixels derived from an intraoperative image, where the grouping of pixels is determined by individual calculation of each pixel using: (a) movement variation of each pixel and (b) intensity values of each pixel;   performing registration using at least two sequential intraoperative images to reconstruct structures in an area of interest;   differentiating moving structures from static structures in the area of interest; and   highlighting anatomical structures on at least one intraoperative image.   
     
     
         10 . The method of  claim 9 , further comprising using a chest x-ray radiographic image as a first intraoperative image.
