COMPUTER AIDED TOMOGRAPHY
In recent years, the use of technology has crept into the toolbox of several violin makers. One of the most interesting application of this kind of machinery, is the study of the best of the classical instruments with Computer Aided Tomography. Not only does it give an insight into the exact geometries of the subject but also very interesting and valuable information about the specific gravity or mass of the materials and how it is dispersed in the instruments.
These scans have been used at the studio in Reykjavik with the generous help of the Domus Medica clinic to study various aspects of the instruments, such as arching geometries and thickness contours as well as density measurements. Future plans include gathering a formidable collection of CT scans of important instruments as a contribution to projects such as those of Terry M. Borman, and the Strad 3D project .
