An example source point cloud set generated by the dart throwing algorithm. (Top left) A 2D coronal slice of the inhale image for test case 6. (Top right) The corresponding 2D coronal slice of the point cloud generated by the dart throwing algorithm applied to the case 6 lung mask. (Bottom left) A 2D sagittal slice of the inhale image for test case 6. (Bottom right) The corresponding 2D sagittal slice of the point cloud generated by the dart throwing algorithm applied to the case 6 lung mask. All lung masks were computed using a simple histogram segmentation.
