Primjena MSCT-a u arheometriji: otkrivanje artefakata ispod odjeće Sv. Pavla

The remains of Saint Paul - archbishop of Constantinople which are kept in Vodnjan parish church were virtually analyzed. Beneath the bishop’s robe, besides the skeletal remains, various artifacts were found. The casket containing remains of the saint was imaged by Multi Slice Computed Tomography (MSCT) device, Somatom 16 (Siemens, Erlangen, Germany), with 16 rows of detectors and the spatial resolution of 30 lp/mm. Scanning parameters were: 120 kVp, 162 mA, protocol – Body Angio Routine, Convolutional Kernel B30f. The slice thickness for the acquisition was 16×0.75 mm and 3 mm for image reconstruction. 2D images were post-processed by Multiplanar Reconstruction (MPR), Volume Rendering Techniques (VRT), and Maximum Intensity Projection (MIP) using software DICOM viewer, Osirix v.3.9.4 (Pixmeo, Geneva, Switzerland). The examination of the nonskeletal material beneath the clothing revealed the unknown object. First, Hounsfield (HU) values of attenuation coefficients were examined to determine the material of which it was made. Afterward, the 3D model was made, and we concluded that the unknown object was a glass object shaped as a vial. The dimensions of this vial were measured using software Osirix, in VRT view. The vial was compared with previously analyzed vials from the chest found in the same parish church. The aim of this comparison was to determine the resemblance in material, size, shape, and to discuss its purpose.
