Fraunhofer creates standard for 3D X-ray analysis of musical instruments

Interesting cooperation has been taking place between the Development Center for X-ray Technology, the Germanisches Nationalmuseum (GNM), and the Chair of X­ray Microscopy (LRM) at the University of Würzburg. Since November 2014, these institutions have been carrying out research as part of the MUSICES project, which is funded for three years by the German Research Foundation (DFG), in order to develop guidelines and procedural methods for the 3D computed tomography of musical instruments. Project researchers are creating robust, well-founded guidelines that will form the basis for international standards in order to ensure that image quality can be reliably compared. The variety of musical instruments that will be covered by the guidelines and specifications to be developed is drawn from the GNM’s comprehensive collection. A few kilometers down the road, the impressive range of X-ray systems at the Development Center for X-ray Technology in Fürth – a collection that is unique in the world – provides the ideal conditions for generating geometrically accurate volume data. Meanwhile, there are facilities for carrying out basic physical research and supporting imaging or analytical methods for reconstructing and evaluating volume data at the LRM in Würzburg and also in the various developer groups at the Development Center for X-ray Technology.
