1. A segmentation method for determining pleural boundaries of a lung, comprising:

  • acquiring image data from an imaging device;

    generating a set of two-dimensional (2D) slice images based on the acquired image data;

    determining, by a processor, a seed voxel in a trachea connected to the lung in a first slice image from the set of 2D slice images;

    applying, by the processor, a region growing process to the first slice image from the set of 2D slice images starting with the seed voxel using a threshold value, wherein a region grown by applying the region growing process corresponds to a lung;

    generating, by the processor, a set of binarized 2D slice images based on the region grown from the seed voxel;

    filtering out, by the processor, connected components of the lung in each slice image of the set of binarized 2D slice images; and

    identifying, by the processor, the pleural boundaries of the lung based on the set of binarized 2D slice images.
