9.4 T MR whole body system
In operation since July 2007, this scanner is the third MR system worldwide with this field strength, the first in Europe and the first 9.4 T scanner built by Siemens. The magnet itself weighs 48 tons and the bore diameter is 82 cm without the gradient coil required for spatial encoding. It has a usable bore size of 60 cm and a head gradient with a maximum gradient strength of 60 mT/m and a slew rate of 400 T/m/s. Its length is almost 4 m and it is placed inside a cage consisting of 600 tons of steel for shielding the magnetic field. This scanner is equipped with a broadband amplifier for multi-nuclei excitation. Hardware for excitation and acquisition, like rf-coils and preamplifiers, are designed and built in our institute.
16.4 T small animal system
This scanner was delivered in August 2007. With a field strength of 16.4 T and a free bore size of 12 cm, it has the strongest horizontal MR magnet worldwide. The 25 tons magnet with 26 cm bore is accommodated in a 220 tons tempered steel enclosure to shield the stray field. It was built by Magnex Scientific (Oxford, UK), the MR hardware was delivered by Bruker Biospin in Karlsruhe. The system is equipped with gradients with a strength of 1 T/m and a high-performance shim system with dynamic shim capacities. State-of-the-art animal handling and supervision equipment is used to prepare the animals for the experiments, to ensure their well-being during anaesthesia and to monitor their physiological parameters during the measurements.
