Non-planar parallel sections: A new approach in digital image analysis of CT volume datasets to improve the assessment of pottery-forming methods
Original language description
The paper presents a newly developed technique for displaying sections of CT reconstructions of pottery fragments. Currently, planar tangential sections are the primary way to show a view perpendicular to the surface of the pottery fragment. This section is essential as it displays structural phenomena critical to interpreting pottery-forming methods. However, the planar tangential sections in curved vessel walls show only a limited area of the wall and, even in this area, the sections cannot display structural phenomena at a constant depth of the wall. Consequently, we designed the construction of a non-planar section that follows the vessel’s shape and can be embedded at a defined depth from the surface so that it maps structural phenomena in defined subsurface layers coaxial with the vessel surface. The newly designed imaging technique was applied to the selection of archaeological pottery from the Czech Republic dated to the La Tène period. We demonstrate the usefulness of the non-planar sections for visual inspection of the diagnostic features related to pottery forming as well as for more accurate calculation of the orientation of the components of the ceramic body.
