Claim One:
1. A computed tomography (CT) alignment system comprising: a data source that stores a first set of CT images and a second set of CT images; a central processing unit (CPU) that processes CT images in the first and second sets stored in the data source by: determining a location of a main carina, a right lobe carina, and a left lobe carina from each CT images in the first and second sets; setting a reference plane based on the location of the main carina, the right lobe carina, and the left lobe carina; setting the main carina as a point of origin; calculating an x-coordinate, a y-coordinate, and a z-coordinate for each pixel in each CT image in the first and second sets based on the point of origin and the reference plane in a XYZ coordinate system; rendering a first three dimensional (3D) model from the CT images in the first set and a second 3D model from the CT images in the second set; associating the x-coordinate, the y-coordinate, and the z-coordinate for each pixel in each CT image with a corresponding voxel in the first and second 3D models; and storing, in the data source, the x-coordinate, the y-coordinate, and the z-coordinate for each voxel in the first 3D model as first voxel position data and the x-coordinate, the y-coordinate, and the z-coordinate for each voxel in the second 3D model as second voxel position data; and a graphics processing unit (GPU) that processes the first and second 3D models based on the first and second voxel position data and synchronously displays the first and second 3D models based on the XYZ coordinate system so that changing or adding views in one of the first and second 3D models results in the same in the other one of the first and second 3D models.
