    • A method for segmenting an object in a volume image, executed at least in part on a computer, renders the volume image data to a two-dimensional display screen showing first, second, and third mutually orthogonal planes in the two-dimensional rendering. One or more operator instructions that identify a plurality of seed points on the rendered volume image are accepted. Two-dimensional coordinates of the identified seed points on the display screen are converted to three-dimensional seed-point coordinates relating to the first, second, and third mutually orthogonal planes a segmentation operation is performed on the volume image according to the converted three-dimensional seed-point coordinates. Segmentation results are displayed on the display screen, relative to the first, second, and third mutually orthogonal planes.

    • A method for processing a digital volume image receives the volume image formed as a stack of image slices, each slice containing voxels and forms a 1:1 mapping of each of the slices, in order, to a corresponding tile in a digital flat volume. The method defines, for at least one voxel in a plurality of voxels in the digital flat volume, a neighborhood that includes the at least one voxel and adjacent voxels that are within the corresponding tile of the voxel, and adjacent voxels to the at least one voxel that are within the preceding tile in the digital flat volume, and adjacent voxels to the voxel that are within the next tile in the digital flat volume. The at least one voxel is rendered according to the adjacent voxels in its defined neighborhood. The volume image having the at least one rendered voxel is displayed.
