Abstract:
A CT alignment system includes a central processing unit (CPU) that processes a plurality of CT images. The CPU determines a location of a main carina from the plurality of CT images and sets the main carina as a point of origin. An x-coordinate, a y-coordinate, and a z-coordinate is calculated for each pixel in each CT image among the plurality of CT images based on the point of origin. A 3D model is rendered from the plurality of CT images and the x-coordinate, the y-coordinate, and the z-coordinate for each pixel in each CT image is associated with a corresponding voxel in the 3D model. The x-coordinate, the y-coordinate, and the z-coordinate for each corresponding voxel in the 3D model is stored as voxel position data. A graphics processing unit (GPU) renders a three dimensional (3D) model based on the plurality of CT images and the voxel position data which is displayed on a display.

Claim (Index 17):
A computed tomography (CT) alignment method comprising:\n setting a slice number for each of a plurality of CT images stored in a memory, wherein a distance between every two adjacent CT images is same along a z-axis in an XYZ coordinate system; selecting a reference CT image, which includes a main carina, from the plurality of CT images; setting a location of the main carina in the reference CT image as an origin of the XYZ coordinate system; calculating an x-coordinate, a y-coordinate, and a z-coordinate for each pixel in each CT image in the plurality of CT images based on the origin and slice numbers in the XYZ coordinate system; storing, in the memory, the x-coordinate, the y-coordinate, and the z-coordinate for each voxel in the 3D model as voxel position data; and rendering and displaying the 3D model on a display.
