At the 2026 Joint Mathematics Meetings (JMM) held in Washington, D.C., Denise Schmutz gave a presentation titled “Asymmetry Conditions for Unique Angular Velocity Reconstruction in Diffraction Tomography” in the AMS Special Session on Tomography Theory and Applications in Honor of Todd Quinto’s 75th Birthday. The talk, based on joint work with Peter Elbau, explored conditions ensuring uniqueness in the reconstruction of rotational motion within the framework of diffraction tomography.

The session celebrated Professor Quinto’s extensive contributions to integral geometry and inverse problems, bringing together colleagues, collaborators, and former students to honor his impact on the field. We are honored to have been part of this special session and grateful for the opportunity to engage with colleagues celebrating Professor Quinto’s lifetime contributions to tomography and inverse problems.

This year, Axel Kittenberger, Denise Schmutz, and Noemi Naujoks once again participated in the Vienna Children’s University, this time with two workshops, each tailored for 20 children aged 7 to 9. Building on last year’s popular topic, we brought back Paula the Sloth to help explain the fascinating world of computed tomography in a playful and accessible way.

The children explored the fundamentals of tomography through a series of interactive stations. These included quizzes, experiments with light and shadow, paint-by-numbers, and exercises demonstrating how mathematics enables us to visualize the inside of objects.

We were excited to see how quickly the children understood complex ideas when given the chance to explore them in a fun way.

From the 3rd to the 6th of December the 17th internal SFB meeting – winter version – took place at the Obergurgl University Centre in Tyrol, Austria. We were very pleased to welcome as invited speakers Giovanni S. Alberti (University of Genoa, Italy), Bernhard Baumann (Medical University of Innsbruck, Austria), and Sebastian Kamann (Liverpool John Moores University), along with early career researchers from different EU and non-EU institutions. The meeting was a great opportunity to foster interdisciplinary communication, promote networking between researchers and experts in the field of tomography, and enjoy the beautiful landscapes of the Tyrolean Alps. The SFB members had the opportunity to present their work and welcome new members.

We look forward to the first SFB Conference of the project “Tomography across the scales”, which will take place in Strobl, Austria, in 2025. Stay tuned!

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.

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.
