2005 NeuroImage  
In the volume-based evaluation, the volume enclosed by the CLASP WM and GM surfaces matched the classified GM volume 13% more accurately than using conventional ASP.  ...  This paper presents a novel method for improving the conventional ASP algorithm by making use of partial volume information through probabilistic classification in order to allow for topology preservation  ...  The process is guided (in a manner that is outlined in the next section) by the use of partial volume CSF in order to insure correct sulcal morphology.  ...

Automatic Delineation of Sulci and Improved Partial Volume Classification for Accurate 3D Voxel-Based Cortical Thickness Estimation from MR [chapter]

Oscar Acosta, Pierrick Bourgeat, Jurgen Fripp, Erik Bonner, Sébastien Ourselin, Olivier Salvado
2008 Lecture Notes in Computer Science  
When using magnetic resonance images (MRI), accuracy may be hampered by artifacts such as partial volume (PV) as the cortex spans only a few voxels.  ...  The aim of this work is to propose a voxel-based cortical thickness estimation method from MR by integrating a mechanism for correcting sulci delineation after an improved partial volume classification  ...  Then, the resulting skeletonized surface combined with the partial volume maps are used to correct the hard segmentations for computing the thickness.  ...
