X-Ray Tomography GroupTOmographic Microscopy and Coherent rAdiology experimenTs
Prof. Stampanoni heads a group of over 20 people, including three staff scientists, two technicians, one controls engineer, and many postdocs and PhD students. The team focuses on the development of tools, both instrumentation and algorithms, for tomographic X-ray imaging, exploiting synchrotron and laboratory sources. The group is engaged in the design and construction of ultra-fast data acquisition systems (stroboscopic coherent X-ray radiology and tomography) to provide dynamic investigation of rapidly evolving systems. The group also intensively develops optimized applications for fast, concurrent post-processing of tomographic data starting from simple normalization corrections to ad-hoc reconstruction and artifact reductions algorithms. Finally, the group investigates, creates and optimizes novel imaging modalities based on the coherent properties of synchrotron radiation and works on the transition of such work to conventional x-ray sources.
New TOMCAT paperOur team in collaboration with scientists from CFEL, MaxIV and ESRF published a work presenting a method for hard X-ray multi-projection imaging. The idea is to split the main beam from a synchrotron or, in the future, from a X-FEL, into multiple beams in order to acquire simultaneous, angularly spaced projection of a sample. This approach provides multiple angular views of the specimens and can provide volumetric information of natural processes and non-reproducible samples in a single shot.
Arttu Miettinen joins the TOMCAT team as PostDocAfter his PhD at the University of Jyväskylä in Finnland in image analysis, Arttu will be working on the stitching and segmentation of large datasets in the framework of the Human Brain Project.
