Claim One:
1. A CT alignment system comprising: a central processing unit (CPU) that processes a plurality of CT image sets, the CPU processes each CT image set by performing the steps including: determining a location of a main carina from a plurality of CT images in the CT image set; 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 among the plurality of CT images based on the point of origin; rendering a 3D model from the plurality of CT images; associating the x-coordinate, the y-coordinate, and the z-coordinate for each pixel in each CT image with a corresponding voxel in the 3D model; and storing the x-coordinate, the y-coordinate, and the z-coordinate for each corresponding voxel in the 3D model as voxel position data; a graphics processing unit (GPU) that processes the 3D model for each of the CT image sets in the plurality of CT image sets based on the voxel position data; and a display that displays a first 3D model for a first processed CT image set and a second 3D model for a second processed CT image set.
