This study compares the penetration depths of two different BrainsWay® Deep TMS (Transcranial Magnetic Stimulation) H-coils and a standard coil (Figure 8 coil). In the study, electrical fields of H-coils and of a Figure 8 coil were measured using a head model. This study demonstrates that the H-coil is able to reach significantly deeper brain areas than those reached by the figure-of-8 coil. Also, it was shown that the H-coils allow for stimulation of several brain regions at the same time.
