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

Abstract. 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 detect and correct these erroneous border areas. Application of this method gives better estimates for the aneurysm volumes. 1 Problem Volume representations of blood vessels acquired by 3D rotational angiography show a clear distinction in gray values between tissue and vessel voxels [1]. These volume representations are very suitable for diagnosing an aneurysm. Physicians may treat an aneurysm by filling it with coils. Therefore, they need to know the volume of the aneurysm. We developed a method for fully-automatic labelling of the aneurysm voxels after which the volume is computed by counting these voxels [2]. We use local distance ...
