  • IFCN Guidelines: International standard for TMS safety
Key Calculation Rules
  • Pulses per train = Frequency (Hz) ร— Train duration (s)
  • Total session time = (Trains ร— Duration) + (Trains-1) ร— ITI
  • Total pulses = Pulses per train ร— Number of trains
  • Weekly load = Total pulses ร— Sessions per week
