Simone Hufnagel was awarded the prize for the best oral presentation at this year's meeting of the German chapter of the "International Society for Magnetic Resonance in Medicine (ISMRM)". In her talk Simone Hufnagel presented a method for the determination of 3D quantitative parameter maps of the heart. This method provides important diagnostic information about the myocardium not only...

On September 6 and 7, 2023, PTB hosted the 25th Annual Meeting of the German Chapter of the International Society for Magnetic Resonance in Medicine (ISMRM, www.ismrm-ds.org) in Berlin. The meeting committee, Sebastian Schmitter (PTB), Susanne Schnell (Universität Greifswald) und Ingolf Sack (Charité Berlin), enjoyed not only the fantastic weather but even more so a record attendance of more...

Active implantable medical devices (AIMDs), such as cardiac pacemakers, have already been implanted in millions of patients worldwide. However, individuals with AIMDs still face limitations in accessing state-of-the-art MRI technology due to the potential risks involved. This restriction is due to the fact that MR scanners employ powerful radiofrequency fields which can result in tissue burns...

Andreas Kofler (PTB) published together with Kirsten Kerkering (PTB), Laura Göschel (Charité-Unviersitätsmedizin Berlin), Ariane Fillmer (PTB) and Christoph Kolbitsch (PTB) an article in IEEE Transactions on Biomedical Engineering.

The article describes a new method for obtaining quantitative MR parameters using adaptive dictionary learning and sparse coding. Instead of applying dictionary...

If an electrical device, or even a simple cable or electrode, is used in an MRI or in its immediate vicinity, this device may interact with the strong electromagnetic fields of the MRI. The consequences can be MR images distorted to the point of uselessness, destroyed equipment and, in the worst case, even injuries to the patient in the scanner. Especially small manufacturers with innovative...

Image reconstruction tasks have seen promising advancements with the use of deep learning (DL) algorithms. However, due to the black-box nature of these algorithms, it is crucial to establish a metric, such as the uncertainty of the network's output, to detect DL artifacts that could be mistaken for pathologies or hinder the accurate detection of actual pathologies. Tackling this issue becomes...

OpenLab MedTec

On 22nd of June, the OpenLab MedTec at the Bundeswehrkrankenhaus (BWKH) in Hamburg, Germany was officially launched. The collaborative project of PTB, BWKH and the Helmut-Schmidt Universität (HSU) in Hamburg hosted the workshop right in the heart of the hospital. Great keynote speakers addressed challenges and opportunities of open-source medical hardware dealing with technical and regulatory...

The acquisition of quantitative (bio-)physical parameter maps of the heart is very challenging due to respiration and heartbeat. Kirsten Kerkering, Tobias Schäffter and Christoph Kolbitsch (PTB), together with clinical partners at the Charité (Jeanette Schulz-Menger), have developed an approach that reduces the scan time by a factor of 5 compared to the clinical standard.

In clinical...
