Claim:
1. A computed tomography (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: 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 and a second 3D model, wherein the main carina, the right lobe carina, and the left lobe carina form an XZ plane in the XYZ coordinate system, and wherein the z-coordinate for each pixel is equal to D*cos α, where D is a distance along a line perpendicular to an XY plane between a CT image that includes the point of origin and a CT image that includes the pixel, and α is an angle at the point of origin between a z-axis and the line perpendicular to the XY plane.
