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...

Patrick Schünke was awarded the "Best Open Source Tool Award" by the "Quantitative MR study group" at this year's conference of the International Society for Magnetic Resonance in Medicine (ISMRM). Patrick Schünke (PTB), Moritz Zaiss (FAU Erlangen), and Kai Herz (MPI Tübingen), along with colleagues from six other institutions, have developed software to enhance the compatibility and...

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...

Successful day for PhD students Johannes Petzold (left) and Berk Silemek (right). At the meeting of the study group on MRI Safety at this year's annual meeting of the International Society for Magnetic Resonance in Medicine (ISMRM) in Toronto, ON, Canada, both were awarded a study group award for their excellent contributions to the field. Johannes received the third prize for his work on "Exper...

In an international collaboration led by University College London, a reference phantom for quantitative MRI imaging of the heart, called T2MES, was developed and tested over twelve months. Spatially resolved measurements of the transverse relaxation time T2 provide clues to edema, inflammation, and other diseases of the myocardium, but in clinical practice measurement results are often...

In a collaboration of PTB departments 1.6 and 8.1 with the Simone Kühne's group at the Max Planck Institute for Human Development in Berlin investigate, it was investigated on a group of volunteers whether and, if so, how the human brain reacts to ultrasound stimuli when these are offered at sound levels below the individual hearing threshold. By functional MRI measurements it was found that a...

The predecessor had served us well for more than 13 years, but eventually it was time to replace it. On May 09, 2023, PTB's new 3T MRI arrived on our premises and was lowered into the historic "Quarzuhrenkeller". Distinguishing feature of the new Cima.X model from Siemens Healthineers, first installation of its kind in Europe, are the powerful gradients. Rated at 200 mT/m they outperform the...

Layla Riemann and Ariane Fillmer were the lead authors of a research paper entitled "Fourier-based decomposition for simultaneous 2-voxel MRS acquisition with 2SPECIAL published in Magnetic Resonance in Medicine (MRM), last summer. Their article was later chosen as an MRM Highlights Pick "… because it demonstrated exemplary reproducible research practices; specifically, they shared example data,...

Since its invention 50 years ago, the development of magnetic resonance imaging (MRI) has been characterized by the pursuit of higher magnetic field strengths. MR scanners with magnets up to 7 T are now a familiar sight in research facilities worldwide, but initiatives to build even more powerful systems have already emerged in many countries. In (and around) Germany, all "ultrahigh field" sites...

In cooperation with the group of Thoralf Niendorf at the Max Delbrück Center (MDC) for Molecular Medicine, Christoph S. Aigner and Sebastian Schmitter from research group 8.14 have investigated questions regarding the feasibility of cardio-MRI at a 14 T magnetic field. Electromagnetic field simulations were used to model various designs of radiofrequency(RF) coils and to evaluate them with...
