Patent ID: 8897534

Claim:
A method for determining a position of a structure located in an object to be investigated by means of X-ray computer tomography, the method comprising the steps: providing a volume data record determined by means of X-ray computer tomography of an object to be investigated; defining a cutting plane through a structure located in the object and to be determined with respect to a spatial position of said structure; determining a cutting data record from the volume data record, which images the object in the cutting plane; binarizing the cutting data record to form a binary data record; determining structure voxels imaging the structure in the binary data record; determining surface voxels imaging an object surface of the object in the binary data record; determining a distance data record in such a way that a distance value, which characterizes a smallest distance of a respective distance voxel from the surface voxels is assigned to each distance voxel of the distance data record; determining the distance voxels corresponding to the structure voxels in the distance data record; and evaluating the distance values of the distance voxels corresponding to the structure voxels.
