Science Meets Kids: The Fascinating World of Computed Tomography

During the 22nd Vienna Children’s University, young students aged 7 to 12 had the opportunity to dive into the fascinating world of computed tomography. Noemi Naujoks, Axel Kittenberger and Denise Schmutz gave an engaging lecture featuring Paula the Sloth as a fun and relatable example for the children.

The lecture was held twice to accommodate the interest, with around 180 children attending both sessions. The interactive format provided the children with not only theoretical knowledge but also practical experiences. Through experiments, a quiz, and special math exercises, the children learned how computed tomography works and the role mathematics plays in it.

PhD defense: Mia Kvåle Løvmo

We are pleased to announce that Mia Kvåle Løvmo, PhD student in the Subproject Imaging of Trapped Particles, defended her PhD thesis with the title “Rotational manipulation of trapped biological samples in acoustofluidic platforms for tomography” on 10 July 2024, and passed with distinction.

Mia’s doctoral study was supervised by Monika Ritsch-Marte, the principal investigator of the Subproject Imaging of Trapped Particles and the Director of the Institute of Biomedical Physics at the Medical University of Innsbruck. Congratulations from the SFB colleagues!

16th SFB Internal Meeting in Strobl

From 1 to 5 July, the 16th SFB internal meeting was held in a nice venue at Wolfgangsee lake in Strobl. The summer meeting between SFB members is an opportunity to share recent progress in the eight different projects and future research directions. We were honoured to have three internationally renowned professors as invited speakers, Markus Grasmair, John Schotland, Ivo Ihrke, Andrea Aspri and Alina Boecker along with researchers and PhD students from Austrian institutions of excellence (RICAM, University of Vienna) and Germany.

During the meeting, we celebrated the 60th birthday of one of the SFB project leaders, Professor Otmar Scherzer.

Professor Otmar Scherzer is an internationally recognised mathematician known for his work in the fields of applied mathematics, particularly in inverse problems, imaging, and numerical analysis.

Mia Kvåle Lømvo received the Best Scientific Paper Award 2024

We are pleased to announce that our SFB member, Mia Kvåle Lømvo, received the Best Scientific Paper Award 2024 of the PhD Programme Image-Guided Diagnosis and Therapy at the Life Science PhD Meeting Innsbruck in April 2024.

This award recognizes Mia’s significant contribution to the paper “Ultrasound-induced reorientation for multi-angle optical coherence tomography” recently published in Nature Communications with Shiyu Deng, Simon Moser, Rainer Leitgeb, Wolfgang Drexler, and Monika Ritsch-Marte.

SFB goes to the 11th IPMS 2024

Two of our SFB members, Peter Elbau and Otmar Scherzer, together with team members from the Computational Science Center (CSC) of the University of Vienna and the Johann Radon Institute for Computational and Applied Mathematics (Ricam), Linz, attended the 11th International Conference “Inverse Problems: Modelling and Simulation” (IPMS 2024) in Malta as invited speakers to mini-symposia. The conference, one of the most prominent in the field, aims to bring together scientists working on inverse problems with different areas of expertise, such as mathematics, physics, engineering, computer science, medicine, and material science to provide a fruitful ground for discussion on the latest advances in theory and foster interdisciplinary collaboration.

New publication in Nature Communications combining acoustic trapping and OCT

The paper titled “Ultrasound-induced reorientation for multi-angle optical coherence tomography” by Mia Kvåle Løvmo, Shiyu Deng, Simon Moser, Rainer Leitgeb, Wolfgang Drexler and Monika Ritsch-Marte was recently published in Nature Communications.

The subprojects in Multi-Modal Imaging and Imaging of Trapped Particles joined forces and developed a novel strategy for acquiring multi-angle OCT by acoustic object reorientation.

Along with a model-based algorithm to fuse the multi-angle data from a priori unknown illumination angles, the strategy enables 3D reconstruction of samples such as embryos and organoids.  

Update June 3, 2024: We are pleased to announce that the paper published in Nature Communications was recently cited in the national newspaper Der Standard. The link to the article can be found here.

International Day of Mathematics

«Playing with Math» was the theme of this year’s International Day of Mathematics on March 14th. Several scientific institutions, including the University of Vienna, the Vienna University of Technology, and the Austrian Academy of Sciences, collaborated to explore intriguing mathematical concepts in a playful manner.

Axel Kittenberger and Noemi Naujoks demonstrated how a computer tomograph works and explained the fascinating mathematics behind it. They showcased the Origami Tomograph developed by CSC, which reconstructs a transparent 3D object from light projections. A special highlight was a quiz that encouraged participants to play the role of a tomograph and guess the underlying object from projection data.

PhD defense: Leopold Veselka

We are happy to announce that Leopold Veselka, PhD student in the Sub-project Quantitative Coupled Physics Imaging, has successfully defended his PhD thesis with the title “Reconstruction of optical parameters in quantitative optical coherence tomography” on 9th of January, 2024.

Leopold’s doctoral study was supervised by Peter Elbau, the principal investigator of the Sub-project Quantitative Coupled Physics Imaging affiliated with the Faculaty of Mathematics, University of Vienna. Congratulations from the SFB colleagues!

Fifteenth Internal SFB Meeting

From 27th to 30th of November the annual SFB Internal Meeting in Obergurgl in Tyrol, Austria, took place. SFB members and invited international participants were giving an insight into their latest research and used the chance to exchange ideas on further research.
Fortunately the weather conditions gave the participants the chance to explore the beautiful area surrounding the University Center in Obergurgl.

PhD defense: Fabian Hinterer

We are happy to announce that Fabian Hinterer, PhD student in Sub-project Tomography with Astronomy, defended successfully his PhD thesis with the title “Inverse Problems in Imaging Applications Across the Scales” on 3rd of November, 2023. A link to his thesis can be found here.

Fabian was a PhD student under the supervision of Ronny Ramlau, principal investigator of Sub-project Tomography in Astronomy, at the Industrial Mathematics Institute at the Johannes Kepler University Linz.

Members of the SFB took part in Fabian’s ceremony and presented him with a joint gift afterwards!

We congratulate!
