1. A method for detecting a trachea of a patient, the method comprising:

  • obtaining a three-dimensional (3D) model of a patient'"'"'s chest;

    generating a plurality of slice images of the 3D model along an axial direction;

    identifying a connected component in each of the plurality of slice images;

    labeling the connected component in a top slice image of the plurality of slice images as an active object;

    associating the connected component in a current slice image of the plurality of slice images with a corresponding connected component in a previous slice image of the plurality of slice images based on a connectivity criterion;

    labeling each connected component in the current slice image associated with a connected component in the previous slice image as the active object; and

    identifying the active object as the trachea, based on a length of the active object.
