We present a method for the segmentation of vessel structures in 3D magnetic resonance angiography (MRA) images with blood-pool contrast agent, allowing artery-vein separation for occluding vessel removal from MIP visualization. The method first uses a front propagation algorithm to select a path along the vessel of interest. Two controlling speed functions are considered, a multi-scale vessel filter, and an approach based on a cylinder shape model. The cylinder based method uses orientation information which is propagated with the front and iteratively updated as the surface expands. Once a vessel of interest is selected, orientation and radius parameters are used to construct a deformable model of the vessel, which is then adapted to the image borders to refine the segmentation of the selected vessel. The results of a comparison with manual segmentations are presented. The extracted centre lines are compared with those from the manual segmentations, showing a mean deviation of 2.55mm for the multi-scale filter, and 1.06mm for the cylinder model, compared to voxel dimensions of 0.93mm. The mean deviation of the final segmentation from the surface of the manual segmentation was 0.59mm. |
