Dear Imaging Enthusiast,

In this issue of the Helmholtz Imaging Newsletter, we highlight new opportunities to get involved, share your work, and shape the future of imaging science across the Helmholtz Association.

Two major calls are now open: the Helmholtz Imaging Project Call 2026, inviting bold, cross-disciplinary research proposals, and the Helmholtz Imaging Best Scientific Image Contest 2026, looking for striking scientific images. Whether you are developing new methods or capturing fascinating visuals of your research, we encourage you to take part.

Want to join our team? We are currently looking for a Team Lead at DKFZ, an exciting opportunity to lead a dedicated support and research team and shape data curation activities across Helmholtz. This role sits right at the intersection of data quality, infrastructure, and AI, contributing to robust, reusable imaging datasets that enable impactful research. We’re a motivated and collaborative team and would love to welcome a new colleague eager to advance imaging science with us. 

Beyond these opportunities, we share updates from across the community, including new team members, highlights from ongoing projects, and selected tools and resources.

As always, we welcome your contributions. Share your imaging-related news and events with us at support@helmholtz-imaging.de. Let’s keep building our vibrant imaging community together.

Happy reading!

Your Helmholtz Imaging team

Helmholtz Imaging Best Scientific Image Contest 2026: Call is Open

What does your research look like? Submit your most captivating scientific images and showcase your research through the power of imaging. The deadline for submissions is May 1, 2026. Previously submitted images are welcome.

Compete for prestigious awards, attractive prizes and wide visibility within and beyond the Helmholtz community, including a feature in the Helmholtz Imaging traveling exhibition.

New this year: In addition to these prizes, winners will receive an exclusive consulting session with our Support Hub team to explore how Helmholtz Imaging can support and extend their research, ranging from image acquisition to advanced image analysis and AI methods. While our Support Hub is always available to all Helmholtz researchers at no costs via our support system, this dedicated exchange offers a uniquely focused and hands-on experience to spark new ideas.

Winning images can also attract media attention: for example, the image “Rare Earth Element Fern” by Kathryn Spiers and Dennis Brückner from DESY and collaborators, awarded in the 2025 contest, was recently featured in GEO magazine.

The award ceremony will take place at the Helmholtz Imaging Conference 2026 in the week of November 9-13 in Leipzig.

Team Updates: Welcomes & Goodbyes

We are delighted to welcome Kris Dreher as the new Team Lead of the Helmholtz Imaging Engineering and Support Unit at DKFZ. With Kris on board, we look forward to continuing and strengthening the unit’s mission of supporting researchers with cutting-edge imaging and data science expertise. 

At the same time, we would like to sincerely thank Fabian Isensee for four years of dedicated leadership of the Support Unit at DKFZ. His vision and collaborative spirit helped shape the team and its connections across the Helmholtz Imaging network. While we are sorry to see him step down from this role, we are glad that he will continue his work at DKFZ, remain active in the scientific environment, and stay closely connected to Helmholtz Imaging and the broader community.

We are also happy to welcome Thomas Roßberg, who recently joined the Helmholtz Imaging Engineering and Support Unit at MDC as a Research Software Engineer. Thomas brings expertise in Earth observation data, satellite imagery, and large-scale data processing. At Helmholtz Imaging, he will contribute to developing software such as PixelPatrol and support scientists involved in large-scale data processing and visualization.

Finally, we say farewell to Jan Philipp Albrecht, a valued member of the Support Unit at MDC and a driving force behind multiple open-source packages for our community, such as Polarity-JaM and Album. We thank him for his contributions and wish him all the best for his next steps.

New on CONNECT: Evaluating Motion and Registration in Adaptive Radiotherapy

Modern radiotherapy can deliver radiation with remarkable precision. However, in areas such as the thorax, breathing motion causes tumors and surrounding organs to move in complex ways, making accurate imaging and dose delivery more challenging.

In a new blog post on the Helmholtz Imaging CONNECT platform, Richard Häcker explores how these challenges affect adaptive radiotherapy and the evaluation of medical image registration methods. Using lung radiotherapy as an example, the article highlights how even small misalignments between CT and MRI scans can influence dose calculations and biomarker analysis.

The post also discusses how learned image representations and new evaluation metrics could improve the assessment of motion and registration algorithms when ground truth data is unavailable.

Tools & Resources, from the Community, for the Community

Following your feedback from the last Helmholtz Imaging Conference, where you asked for more tools and resources, we introduced this new newsletter section dedicated to sharing open, practical solutions from the community. So, here we go:

Tool spotlight: LUCYD, restoration of volumetric microscopy images

Living foraminifera captured with a PIScO (Plankton Imaging with Scanning Optics) underwater camera in the deep tropical Atlantic

How can we recover useful information from noisy and blurred microscopy images? LUCYD is a new method for restoring volumetric microscopy images that combines the Richardson–Lucy deconvolution approach with deep feature fusion from a fully convolutional network. By integrating the image formation process into a feature-driven restoration model, LUCYD aims to improve image quality while reducing computational costs and maintaining interpretability.

The tool was developed by Tomáš Chobola, Gesine Müller, Veit Dausmann, Anton Theileis, Jan Taucher, Jan Huisken, and Tingying Peng.

Call for Experts: Contribute to Europe’s AI-in-Science Agenda

The Horizon Europe-funded SCIANCE initiative invites experts to join its AI in Science Working Groups, a unique opportunity to help shape the future of AI in scientific research across Europe. SCIANCE contributes to building RAISE (Resource for AI Science in Europe), a virtual research institute for excellent European research on and with AI – including AI-driven imaging and image data analysis – providing European researchers with access to expertise, data, and computational resources.

Selected participants will contribute to the development of a Strategic Research & Innovation Agenda (SRIA), identifying priorities, challenges, and opportunities at the intersection of AI and science, naturally with a strong focus on data- and image-intensive research domains

The working groups bring together interdisciplinary expertise to address key topics such as AI methods and tools, research infrastructures, data stewardship, and domain-specific applications, including imaging workflows and multimodal data integration.

If you are a recognized expert, emerging leader, infrastructure operator, AI innovator, or cross-disciplinary researcher working with imaging data across domains, and want to shape European AI in science priorities at policy and infrastructure level, consider applying. The deadline is April 10. 2026.

We would also be very happy to hear from you if you apply – and especially if you are selected to join one of the working groups.

When AI Performance Misleads: Watch Annika Reinke’s Lecture

Strong results on paper do not always translate into reliable performance in practice. In her lecture “When AI Performance Misleads: From Success in Papers to Failure in Practice,” Annika Reinke discusses why AI models can fail when deployed in real-world settings. The talk highlights common validation pitfalls and offers practical guidance for improving the reliability and trustworthiness of AI systems.

DESY Imaging Technology Featured on ZDF’s Terra X

How can scientists read texts that have remained hidden for thousands of years? A recent Terra X episode showcases how advanced imaging technologies make this possible. Christian Schroer, one of Helmholtz Imaging’s Center Coordinators, and colleagues from DESY, the University of Hamburg and use a mobile X-ray scanner to look inside sealed Mesopotamian clay envelopes – without opening them – revealing ancient cuneiform tablets.

A fascinating example of how interdisciplinary research unlocks the secrets of the past.
