Abstract
Paleopathology and anthropology are fields of research which have benefited from the use of diagnostic imaging since its introduction in the clinical setting. The deriving discipline, that is, paleoimaging, has effectively employed several diagnostic techniques. However, while Multi-Slice Computed Tomography (MSCT) has found its role in paleoimaging, Cone-Beam Computed Tomography (CBCT), despite its several advantages with regard to MSCT, is still struggling to find a clear position in this field. The aim of our study is to evaluate the possible advantages CBCT could bring to paleoimaging. We describe the characteristics and role of CBCT in clinical applications, in forensic and legal medicine, and in paleopathology. We report the study of an ancient mandible by means of CBCT and MSCT, in order to compare the quality of the images in terms of spatial resolution. CBCT allows to obtain good quality images of mineralized tissues. Moreover, the possibility of imaging metallic manufacts makes the technique suitable for the study not only of bony remains, but also of museum and archaeological artifacts. Our study highlights the strengths of CBCT as a valid imaging technique for the study of ancient bone remains and manufacts. A revision of the current uses of CBCT is provided and gives insights into the possible role it can cover in bioarchaeological studies. Further evaluation is needed in terms of possible applications of this technique to paleopathology. We strongly encourage the use of CBCT in paleoimaging, and suggest a broader application of the technique to the study of archaeological samples.
