The exceptional field strength is enabled by high-temperature superconductors (HTS). By eliminating the need for liquid helium and relying on conductive cooling instead, HTS technology enables more compact, lighter-weight magnet systems while supporting substantially higher magnetic field strengths..
Conventional MRI magnets reach their physical limits at around 12 Tesla. In clinical practice, MRI systems typically operate at field strengths between 1.5 and 3 Tesla. The world’s most powerful research MRI currently in operation, with a field strength of 11.7 Tesla, is located in Paris.
Technological Pioneering from Magdeburg
Neoscan Solutions was awarded the contract to develop and manufacture the magnet following an international selection process. For the company, the project marks the beginning of a new generation of MRI technology.
A total of approximately 500 kilometers of superconducting wire will be used in the magnet. The cryostat, which houses the magnet, has already been completed.
New Opportunities for Brain Research
The 14 Tesla MRI system is expected to provide unprecedented insights into the structure and function of the human brain. The higher field strength improves spatial resolution, making it possible to visualize extremely fine neural structures. It will also enable researchers to study dynamic processes in the brain with greater precision and, in the future, imaging metabolites and metabolic processes.
At 14 Tesla, the system significantly surpasses previous technological limits and establishes a new world record in MRI technology.
Stefan Röll, Managing Director: “The start of the winding process is the result of a significant R&D effort. It includes extensive simulations, partially invasive material and sub-component testing under operating conditions, as well as construction of high end components, supplier selection, and development of the two precision winding tools. Compared with the original, highly ambitious timeline, the project is one year behind schedule. However, we have gained enormous confidence that we are building the to meet its specifications. We are especially grateful for the collaboration with the Magnet Committee of the DYNAMIC Consortium in this project.”
David Norris, professoir in MR physics related to applications in the cognitive neurosciences at Radboud University and project leader: "The completion of the 14 Tesla magnet marks a major milestone for the DYNAMIC project. I am deeply impressed by the outstanding work Neoscan has done in overcoming the technical challenges involved in building this pioneering magnet. We are excited to put it to use in the construction of the world’s most powerful MRI scanner.”
