X-ray computed tomography for non-destructive analysis of early Medieval swords

The analysis of early Medieval swords is of great significance due to the eminent position of the find category in the study of the early Medieval period. X-ray computed tomography is a non-destructive analytical method permitting the collection of data that otherwise could only be gathered with considerable effort and much damage to the object. Beyond the usual morphological and dimensional parameters, the method allows for the fast and accurate gathering of knowledge about the construction and manufacturing processes of sword blades and can also be applied to block-lifted swords. Preservation condition and related artifacts caused by beam hardening may be limiting factors; however, in most instances interpretation of the data remains possible.
