Fully-Automatic Correction of the Erroneous Border Areas of an Aneurysm

Volume representations of blood vessels acquired by 3D ro- tational angiography are very suitable for diagnosing an aneurysm. We presented a fully-automatic aneurysm labelling method in a previous pa- per. In some cases, a portion of a \normal" vessel part connected to the aneurysm is incorrectly labelled as aneurysm. We developed a method to detect and correct these erroneous border areas. Application of this method gives better estimates for the aneurysm volumes.
