Shifting of the Aneurysm Necks for Enhanced Aneurysm Labelling

Volume representations of blood vessels acquired by 3D rotational angiography are very suitable for diagnosing an aneurysm. We presented a fully-automatic aneurysm labelling method in a previous paper. In some cases, a portion of a “normal” vessel part connected to the aneurysm is incorrectly labelled as aneurysm. We developed a method to shift the erroneous borders as close to the real aneurysm as possible. Application of this method gives better estimates for the aneurysm volumes.
