Patent ID: 8107707

Claim:
A system ( 500 ) for visualizing a vascular structure ( 306 ) represented by a three-dimensional dataset in which respective voxel values are associated with respective voxels, the system comprising: means ( 502 ) for establishing respective filling values ( 314 ), based on the voxel values, associated with respective positions in the vascular structure, a respective filling value being indicative of an amount of blood in a neighborhood of the respective position in the vascular structure; means ( 504 ) for determining respective minimum filling values ( 316 ) associated with the respective positions in the vascular structure, a respective minimum filling value being a minimum of the filling values ( 314 ) associated with positions upstream of a respective position; means ( 506 ) for computing respective deficiency values ( 318 ) associated with the respective positions in the vascular structure, a respective deficiency value being computed in dependence on the filling value ( 314 ) associated with the respective position and the minimum filling value ( 316 ) associated with the respective position; and an output ( 514 ) for providing a visualization ( 408 ) in dependence on the deficiency values.
