rTMS stands for RepetitiveTMS, where thousands of repetitive pulses are generated to deliver magnetic waves into the prefrontal cortex of the brain by figure-8 coils. These older figure-8 coils used by all previous TMS machines are placed on the left side of the brain and are limited in how far the magnetic waves can penetrate into that section of the brain. dTMS which stands for Deep TMS is a newer technology developed by Brainsway Ltd, which uses a three-dimensional helmet design that is placed on top of the head. Its advantage lies in its combined ability to encompass a broader surface area of the brain stimulating deeper structures more directly within the brain, and to also more efficiently target those crucial structures in the brain linked to mood control and mental health conditions. A 2019 study published in the Journal of Psychiatric Research found the difference between these treatments to significantly favor Deep TMS, noting that patients with depression reached higher rates of response under the Deep TMS treatment, when compared to the traditional rTMS. Brainsway’s Deep TMS system is currently the only system on the market that is cleared by the FDA to treat OCD, anxious depression and smoking cessation.
