The seminar entitled Computed Tomography and High-Energy Diffraction – From Technical Applications to Cultural Heritage Objects will be given by Dr. Daniel Vavřík from the Institute of Theoretical and Applied Mechanics, Czech Academy of Sciences on April 23, 2026, at 10:00 am in the IPM lecture hall. The seminar will be held in Czech.
The seminar will present the basic principles of laboratory X-ray tomography, as well as its less traditional variants—dual-energy tomography, triggered tomography, and 4D tomography. In the field of materials research, the seminar will explore the possibilities of studying time-dependent processes—fracture mechanics, deformation of 3D structures, and beam vibration. In the context of cultural heritage research, various methods for processing tomographic data will be demonstrated to reveal information that would otherwise be difficult to access—the stratigraphy of Gothic panel paintings, the reading of old prints, and the study of ancient lead artifacts and cuneiform tablets. Applications of very fast laboratory high-energy X-ray diffraction for the study of phase changes in steel will also be demonstrated—such phenomena can otherwise only be investigated at synchrotron sources.
