Networks & Platforms

We actively contribute to national and international research networks and platforms, fostering collaboration in AI and medical imaging. Our focus is on scalable data analysis, federated learning, and robust research software to drive innovation. By integrating cutting-edge methods into clinical and scientific workflows, we enhance AI’s real-world impact.

Kaapana

The image displays a medical imaging interface featuring multiple scans, such as MRIs and CTs, arranged in a grid. Selected images have red markers, and a detailed metadata panel is visible on the right, showing information about a specific scan. The overall theme focuses on medical diagnostics.

Kaapana is an open-source toolkit for state-of-the-art platform provisioning in the field of medical data analysis. The applications comprise AI-based workflows and federated learning scenarios with a focus on radiological and radiotherapeutic imaging.

Obtaining large amounts of medical data necessary for developing and training modern machine learning methods is an extremely challenging effort that often fails in a multi-center setting, e.g. due to technical, organizational and legal hurdles. A federated approach where the data remains under the authority of the individual institutions and is only processed on-site is ideally suited to overcome these difficulties.

Kaapana provides a framework and a set of tools for sharing data processing algorithms, for standardized workflow design and execution as well as for performing distributed method development. This facilitates data analysis in a compliant way enabling researchers and clinicians to perform large-scale multi-center studies.

By adhering to established standards and by adopting widely used open technologies for private cloud development and containerized data processing, Kaapana integrates seamlessly with the existing clinical IT infrastructure, such as the Picture Archiving and Communication System (PACS), and ensures modularity and easy extensibility.

RACOON – RAdiological COOperative Network

The RACOON initiative establishes a nation-wide infrastructure for the structured acquisition, processing and analysis of radiological imaging data. By connecting all 38 university clinics providing images including structured reports of the diagnosis, it is able to form a solid foundation for radiological research in Germany. The established infrastructure and collected data sets are of use for early detection systems and AI supported medical decision support systems and therefore form a solid foundation towards archiving pandemic preparedness.
The department of medical image computing provides its expertise in building federated machine learning infrastructures. It contributes the Kaapana software platform allowing easy cohort definition, centralized and federated machine learning for image analysis. Furthermore, method sharing between the partners is streamlined by providing supporting execution of containerized methods either on-site as part of the local RACOON-Nodes or in the central component as part of RACOON-Central.

Effective Privacy-Preserving Adaptation of Foundation Models for Medical Tasks

Foundation models in the vision domain are large machine learning models pre-trained on vast amounts of natural images to extract relevant features from their input data. In the PAFMIM project, we aim at adapting existing foundation models to sensitive medical images, such as CT and MRI data. The challenges include ensuring a good performance of the models on medical images and guaranteeing privacy for the medical images. Our project addresses the challenges in a joint approach combining competencies from the perspective of medical image computing and privacy-preserving machine learning.

Quality-controlled analysis of large population-based imaging datasets

In this project, we explore approaches for conducting quality controlled image analysis in large health studies like the German National Cohort or UK Biobank. We specifically focus on efficient and reliable techniques for performing quality control on machine-generated image segmentations in the absence of ground truth, as a prerequisite for ensuring the correctness of image-based measurements. To establish time and annotation efficient solutions that are largely applicable on various organs of interest, we investigate the use of uncertainty quantification methods as an efficient means for estimating error. We closely examine goal-specific performance measures to assess how well error estimators are suited for accomplishing important tasks of segmentation quality control. Beyond this, we focus on the development of DL based techniques for detecting and repairing notorious MR imaging artifacts that otherwise require tedious manual effort to handle, and that are known to corrupt measurements derived from affected imaging data.
