Abstract:
1. A method for planning or guiding an intervention procedure in a 3D tubular structure comprising rendering and displaying the 3D tubular structure's pre-procedural curved planar reformat view, wherein the rendering of the curved planar reformat view comprises smoothing a center axis of the 3D tubular structure by removing those parts of the center axis that protrude in a direction of a latitudinal vector that is orthogonal to the center axis, and following or steering the viewing direction of the curved planar reformat view by the viewing angle on a segmented or raw representation of the 3D tubular structure's rendered voxel volume to be visualized or to the C-arm geometry of a 3D rotational angiography device's C-arm system, wherein the viewing angle on the 3D tubular structure's rendered voxel volume is manipulated in such a way that the corresponding curved planar reformat view does not change, by rotating the viewing angle about a latitudinal direction so that the 3D view allows the selection of a view in which no overlap between different vessel segments occurs, wherein the viewing angle rotation is a unique rotation by making an up-vector of the curved planar reformat view on the 3D tubular structure's voxel data set correspond to the up-vector of the 3D rotational angiography device's C-arm system for a given yaw position, wherein the up-vector is given by the y-axis of the reformatted 2D view port.
