Usually spatial encoding in MRI is performed by using three orthogonal spatially varying fields. However, a high number of individual localized coil elements add further degrees of freedom. This offers new exciting possibilities for novel imaging techniques (some of which are also invented and patented by us).. Due to spatial restrictions, higher maximum gradient amplitudes can be achieved locally before running into physiological limits, mainly stimulations of peripheral nerves. Now novel high-channel matrix gradient coils can be designed from individual preassembled subgroups through implementation.
- High number of individual elements for additional degrees of freedom
- Coil construction from individual, pre-manufactured elements
- Each element shielded and balanced for force and torque
- MRI exams become easier, faster and more precise.
