MRi-B91
The coil is designed for use in MRi scanners up to 4 Tesla with biphasic Waveform Standard mode. The coil is suitable for focused stimulation. Symmetrical placed inside the housing so the magnetic field on both sides is equal.
The MRi-B91 has a temperature sensor, which turns the stimulator off, when the coil reaches a specified maximum temperature.
