Claim One:
1. A computer-based method for locating one or more landmarks using an MR image of a brain, the method including the following automatic steps: (a) identifying a region of interest (ROI) with a plane of the MR image, the plane containing the landmark(s); (b) binarising the plane of the MR image into foreground and background voxels based on at least one threshold selected using anatomical knowledge; (c) identifying a set of object voxels from the foreground voxels, the set of object voxels excluding voxels which were only classified as foreground voxels due to proximity of cortical and non-cortical structures; (d) identifying object voxels from the background voxels due to the partial volume effect and/or morphological erosion/opening; and (e) identifying the one or more landmarks using the object voxel.
