The present invention relates to guidance during a medical intervention. In order to provide an improved navigation support with a facilitated setup, a system () for navigation support is provided. An image data input () receives a plurality of acquired 2D X-ray images of a subject's body from different angles. A set of markers, which are visible in X-ray images and which are detectable by a navigation system, is assigned to the subject. A marker detecting arrangement () is provided that detects a current spatial location of the markers assigned to the subject. A data processor () reconstructs a 3D volume of the subject based on the plurality of 2D X-ray images. At least a part of the markers is arranged outside the volume covered by the reconstructed 3D volume of the subject, while the markers are visible in the 2D X-ray images. The data processor () identifies the markers in the 2D X-ray images based on image data of the plurality of 2D X-ray images outside the 3D volume and determines a spatial location of the markers in relation to the 3D volume of the subject. The data processor () also registers the reconstructed 3D volume of the subject to a current spatial position of the subject based on the detected current spatial location of the markers and the determined spatial location of the markers in relation to the 3D volume of the subject. An output interface () provides the registered reconstructed 3D volume for navigation.

A diffusion data processing apparatus comprising a segmenter arranged to segment the diffusion tensor data according to at least one segmentation model representing at least part of a fiber bundle. The segmentation model may comprise macroscopic and/or microscopic information. This leads to a segmentation of the fiber bundle that is robust and less influenced by non-perfections of the data set, such as low signal-to-noise ratio, partial voluming, or other imaging artifacts.

Fibre tracking on the basis of macroscopic information

A method of deriving a directional structure from an object dataset is proposed. The object dataset assigns local directions to positions in a multidimensional geometrical space. For example the local directions concern local flow directions in a diffusion tensor magnetic resonance image at least one 'region of interest' is selected on the basis of spatial functional information, such as an fMRI image, time correlation of an fMRI image series with a functional paradigm or an anatomical image. These 'region of interest' are employed to initialize a fibre tracking to derive the directional structure that represents the nervous fibre system.
