Pig experiment. Maximal temperature increases Δ TMax measured on the distal (Probe 1) and proximal (Probe 2) DBS electrodes during 3.0T and 1.5T scanning of the pig. The 3.0T data were averaged over two probe locations and measurement runs 1 through 5. The highest recorded values are listed below the averages. The 1.5T data were recorded during a single run and therefore individual measurements by both probes are shown.
| Pulse Sequence | 3.0T | 1.5T |
