Description of original award (Fiscal Year 2008, $171,215)

This research aims to improve sex diagnosis of crania by constructing an atlas of 3-dimensional bone models obtained from CT scans. A bone atlas is comprised of a database of models used to represent individual bones. From an atlas, statistical variation of morphology within populations can be computed to improve sex discrimination. By improving sex discrimination, anthropologists will be more likely to correctly identify an individual by his/her remains. This will help to eliminate the backlog of unidentified human remains.


This continuation proposal focuses on creating the atlas of 3-dimensional skull models obtained from the computed tomography (CT) scans during the first year of the project. The researchers will perform the automatic measurement of landmarks and cranial volumetric measurement that can be used to quantify cranial morphology. The CT data will be cross-validated with traditional methods of biological anthropology and radiography, thus serving to increase reliability and applicability. ca/ncf
