Open-source practices and resources in MRI have increased substantially over the past years. This trend started with software and data being published open-source, but more recently open-source hardware designs are increasingly becoming available, too. The plentitude of open-source soft- and hardware products that are meanwhile available for all kind of MRI related purposes makes it increasingly...

Signal generation in magnetic resonance imaging (MRI) scanners relies on strong radio frequency fields. Monitoring and limiting the local energy deposition in the patient's body, measured via the specific absorption rate (SAR), represents a major challenge, especially when working with several transmit antennas in parallel. The SAR distribution cannot be measured directly but must be calculated...

Physiological parameter estimation by MRI is affected by intrinsic ambiguity in the data such as noise or model inaccuracies. Edengenet Dejene (PTB 8.14), together with Winfried Brenner (Charité), Marcus R. Makowski (TU München), and Christoph Kolbitsch (PTB 8.14), now developed a method for the uncertainty quantification of physiological parameters in dynamic contrast enhanced MRI of the liver....

Jana Zhang was awarded the "Schnieder-Preis JUNGE MACHERIN" by acatech — Deutsche Akademie der Technikwissenschaften for her Master's thesis "Respiratory Motion-Corrected T1 Mapping of the Abdomen". This prize was awarded to Ms Zhang for her outstanding scientific achievements and also for her high level of social commitment. Ms Zhang studied at the TU Berlin and her work was supervised by Dr...

Open-source low-field MRI offers completely new opportunity for health care. More than 30 international experts met in Berlin to kick-off a 3-year project to build, characterize and evaluate three open-source low-field MR scanners. The project will cover hardware and software development, physics-informed deep-learning image reconstruction and uncertainty assessment and MDR-ready documentation —...

Natalie Schön was awarded with the third place of the Gorter Award at this year's annual meeting of the German chapter of the ISMRM. The Gorter Award honours the currently best publications of young scientists in the field of magnetic resonance imaging in medicine or natural science.

Natalie Schön presented the publication of the topic "Respiration resolved body models in electromagnetic...

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 25^th 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 Fabian Altekrüger (TU Berlin), Fatima Antarou Ba (TU Berlin), Christoph Kolbitsch(PTB), Evangelos Papoutsellis (Finden Ltd), David Schote (PTB), Clemens Sirotenko (WIAS), Felix Frederik Zimmermann (PTB) and Kostas Papafitsoros (QMUL) an article in SIAM Imaging Sciences.

The article describes a new method for learning regularization parameter-maps...
