We deal with image processing applied to 3D analysis of vascular morphology in magnetic resonance angiography (MRA) images. It is, above all, a state-of- the-art survey. Both filtering and segmentation techniques are discussed. We briefly describe out most recent contribution: an anisotropic non-linear filter which improves visualization to small blood vessels. Enhancement of small vessels is obtained by combining a directional L-filter applied according to the locally estimated orientation of image content and a 2D laplacian orthogonal to this orientation.
