The most important aspect of MRI-compatible rehabilitation is thebidirectional compatibility problems between the MRI device and the rehab equipment. To ensure bidirectional compatibility, the device must not disturb the imaging process or cause image interferences. At the same time, the performance of the device must not be affected by the imaging process. The Sabancı University searched fornon-magnetic, non-conductive polymer ball bearings that were not only maintenance-free but also had a long service life.
The components located in the MRI area have to be MRI compatibledue to the strong magnetic field. This also applies to bearings with low friction. In this area, a xirodur B180 polymer ball bearing with glass ballsis used. In addition to the mentioned requirements, and due to their non-magnetic and low-friction properties, they are lubrication and maintenance-free and have a long service life. As too high friction has negative consequences for transmitting the forces to the patient, the xiros polymer ball bearings ensure that the patient is optimally supported.
