<p>A method of visualizing a simulated fly through a source volume, comprising the steps of obtaining a three-dimensional data set defining said source volume in a voxel-wise manner by assigning to each voxel at least one value representing a measure of a physical characteristic of the corresponding section of the source volume, choosing a viewing direction with respect to the source volume, performing volume slicing into a predetermined number N of parallel slices, wherein N is significantly smaller than a number M of possible parallel slices corresponding to unlimited volume slicing through the entire source volume, the parallel slices being orthogonal to the viewing direction, each slice being represented by an image obtained by processing said three-dimensional data set, the first, i. e. the upmost, slice being determined by a start position, performing volume rendering to build up a volume rendered 3D-image formed of N superimposed images corresponding to said N volume slices resulting in a viewing volume that is a comparatively small portion of the whole source volume, displaying the volume rendered 3D-image, and simulating a fly through said source volume by repeating the volume slicing and volume rendering with continuously differing start positions. <IMAGE></p> |
