Micro-CT and OCT data of defleshing marks on human remains from a cooking pit, prehistoric Denmark: A BODY-POLITICS dataset

Overview To reveal the micro morphology of cut marks, the skeletal element was imaged using x-ray micro computed tomography (micro-CT) and optical coherence tomography (OCT). The datset consists of: A 2× binned and cropped version of the micro-CT data (2 GB, zip) the OCT data (73 MB, zip) interactive PDF files of surface renderings of three cut marks Methods The entire sample was micro-CT scanned using a CoreTOM system (TESCAN GROUP, Brno, Czech Republic) equipped with an integrating detector and using the following parameters: x-ray tube voltage = 80 kVp, x-ray tube power = 15 W, integration time = 400 ms, number of projections = 4283, spatial resolution = 0.08 mm isotropic, averages = 5, acquisition time = 9 h and 48 min. Following acquisition, x-ray projection images were reconstructed into tomography slices using the software Panthera (TESCAN GROUP, Brno, Czech Republic). For OCT a single potential cut mark was targeted and this depression was scanned using a TEL321C1/M 1300 nm spectral domain system (Thorlabs, Newton, NJ, USA) using the following parameters: scan area = 1.5 × 2.53 × 2.51 mm, spatial resolution = 0.03 × 0.03 × 0.0245 mm. Tomography slices acquired by micro-CT and OCT were further analyzed using ImageJ 1.50e and Amira version 5.3.3 to construct virtual profile slices and surface renderings of the cut marks.
