Transcranial Magnetic Stimulation or TMS uses electromagnetic pulses to stimulate areas of the brain thought to be associated with depression. Electroconvulsive therapy or ECT use electricity to induce a generalized seizure which is thought to be therapeutic. The placement of the ECT pads is relatively strategic to areas of the brain associated with depression, but is not as precisely determined as with TMS. 

The Brainsway deep TMS (transcranial magnetic stimulation) employs a patented H1 coil which differs from all other TMS devices on the market that use a figure 8 coil. This figure 8 coil stimulates the brain more superficially and narrowly. The Brainsway device was developed to reach more broadly and deeper into the brain where many of the structures associated with mood and other brain disorders lie.
