There is no research anywhere that shows that “Deep” TMS has any advantage over standard TMS in the treatment of Depression. When the FDA approved the Brainsway magnet used to treat depression (the Hesed-1 coil) in 2013, they did so by determining it to be equivalent to the NeuroStar TMS magnet. The FDA considers them to be in the same therapeutic category and makes no distinction between them. The area of the brain being treated in Depression is in the cortex or outer layer of the brain, and all TMS devices FDA approved for use in Depression are designed to reach this target. There is a documented higher seizure rate with Deep TMS devices however.
