From 10th to 21st of October, the first two workshop-weeks of the RICAM Special Semester “Tomography across the Scales” took place at the Johann Radon Institute for Computational and Applied Mathematics in Linz. There, Fabian Hinterer, Simon Hubmer, Michael Quellmalz, Ekaterina Sherina and Leopold Veselka, all members of the mathematical subprojects within the SFB project, were invited to present their latest scientific advances to an audience of experts in the various fields of Inverse Problems. Furthermore, the members got the chance to exchange ideas with other researchers and to benefit from external input. We express our gratitude to the organizers for the invitation and the hospitality during these perfectly organized workshops!
Currently, the autumn school as part of the Special Semester “Tomography Across the Scales” takes places at the RICAM in Linz. Peter Elbau, one of our project leaders, was invited to give an introductory lecture on the mathematics behind optical coherence tomography. The audience, including several members of SFB, warmly welcomed the intuitive and very well presented lecture on this highly complex topic.
The online Workshop at the Erwin Schrödinger International Institute for Mathematics and Physics (ESI) has just started. This is a two-weeks event with more than 50 international researchers participating.
In the first week (March, 15th – 18th), we have mainly talks from applied mathematicians presenting results on tomographic reconstructions while the second week (March, 23th – 25th) covers the practical applications of such methods in astronomy and medical imaging. See the full program here.
Registration is free. You just have to contact Peter Elbau.
The workshop is organized within this SFB research program and is centered around the mathematical and experimental problems related to the applications studied in this project, involving adaptive optics, optical coherence tomography, photoacoustics, and superresolution imaging.
The 5th Internal Meeting and the 4th Member Workshop took place online on September 1st and 2nd, respectively. After the cancellation of the previous meetings due to Covid-19, we managed to meet after a long time (at least online).
In the internal meeting, we had the opportunity to listen to interesting talks from external members of the SFB and participate in special sessions of the collaborating sub-projects. The member workshop consisted of member talks and talks from associated members with potential application to the scope of the SFB. The members elect Simon Hubmer and Ekaterina Sherina as the new member speaker and vice-speaker, respectively.
Hopefully we can meet in person again in Bad Mitterndorf at the end of November.
Last week (02.03 – 06.03) took place in Kefermarkt the first winter school of the Austrian Study Foundation (Österreichische Studienstiftung). That was the fourth seminar organized by the Austrian Academy of Sciences (Österreichische Akademie der Wissenschaften) with the title “Applied mathematics: as useful as exciting”.
Selected pupils from schools around Austria had the possibility to learn and develop themselves applications of mathematics in everyday life. The four topics where: Financial mathematics, mathematical methods in Tomography, graph theory and mathematical modeling of sound.
Axel Kittenberger and Leonidas Mindrinos (University of Vienna) presented the fundamentals of the Radon transform, its properties and application to tomography. The students made 3D origami objects, image them with a system imitating an optical tomographic setup and then obtain the reconstructed pictures. Günter Auzinger (JKU Linz) addressed also the mathematics of sound propagation. The pupils had the opportunity to answer questions like: What makes the pitch of a musical instrument, what makes the sound and what does this mean for the human voice.
Wolfgang Drexler (PI of the sub-project “Multi-Modal Imaging”) discusses about his work on Optical Coherence Tomography and his new role as co-chair of BiOS at SPIE Photonics West, one of the biggest biomedical optics, and imaging conference. Read the whole interview here.
Otmar Scherzer was a member of the organizing committee of the “Reconstruction Methods for Inverse Problems” workshop in Banff, Canada, June 23-28, 2019. This workshop brought together researchers working on inverse problems coming from medical imaging, non destructive testing, computer vision and geophysics. The PI of sub-project “Quantitative Coupled Physics Imaging”, Peter Elbau and the post-doctoral researcher of the sub-project “Tomography with Uncertainties”, Ekaterina Sherina presented their recent work related to our SFB project.
Otmar Scherzer gave an interview for the newspaper “die Presse” describing the scopes of the sub-project Quantitative Imaging. You can read it here (in german). An article (in english) describing the mathematics involved in emerging imaging techniques appeared in Innovation Origins.
