The Use of Transcranial Focused Ultrasound for the Treatment of Depression and Anxiety

The FDA has determined that power intensity limits of 720 mW/cm squared at 2 megaHertz is safe for clinical use; the proposed equipment works within these parameters. Furthermore, monitoring sessions up to one hour as proposed in this study are routinely used in patients even with acute brain injury at 2 megaHertz without any reports of complications induced by the ultrasound device. No brain heating, cavitation or bleeding has been identified with the proposed equipment and protocol. For each individual safety can be followed by performing a selective mental status exam at each session completion.
