Patients will undergo ten to thirty minutes of transcranial ultrasound treatment. The sonification device will be aimed at the caudate. Targeting will include reference to scalp fiducials based on the obtained MRI; confirmation of target accuracy will either be obtained by Doppler waveform confirmation or optical tracking technology which co-registers patient neuroimaging with real space.

The DWL Doppler ultrasound device enables visual and auditory wave form confirmation of cerebral arteries, and optical tracking technology (eg, AntNeuro Visor2 system) may be used in tandem with the Brainsonix Pulsar 1002 ultrasound device to track a patient's brain in virtual space as well as their physical location, thereby ensuring accurate placement.

This instrument is designed to evaluate the severity of symptoms for Obsessive Compulsive Disorder. The Y-BOC is composed of 10 items, and uses a scale that ranges from 0-4 based on the individuals mark going from 0 as no symptoms to 4 extreme symptoms for a total possible score of 40. Severity range is as follows: subclinical OCD is indicated by scores ranging from 0-7, mild OCD is indicated by scores ranging from 8-15, moderate OCD is indicated by scores ranging from 16-23, severe OCD is indicated by scores ranging from 24-31, and extreme OCS is indicated by scores ranging from 32-40. Moderate to extreme symptoms are clinically significant. For treatment of OCD, a clinically significant change must decrease greater than or equal to 35% relative to baseline. This amount of change is also most predictive of treatment response.

The BAI is a 21-question multiple-choice self-report inventory that is used for measuring the severity of anxiety symptoms. Each of the 21 items asks whether the patient has experienced various anxiety symptoms in the last two weeks, and if so, how severely. Each question/answer is scored on a scale value of "0" (not at all) to "3" (severely). Higher total scores indicate more severe anxiety symptoms. The maximum total score possible is 63 points. The standard cutoff scores are: 0-7 = minimal anxiety; 8-15 = mild anxiety; 16-25 = moderate anxiety; 26-63 = severe anxiety. A reduction in score by at least 30% is considered clinically meaningful.

The BDI-II is a 21-question multiple-choice self-report inventory. Each question involves four possible responses, ranging in intensity from "0" (this item does not apply) to "3" (this item applies severely). The test is scored as the sum of all of the response values; this number is used to determine the severity of depressive symptoms. A score of 0 to 3 is possible for each question with a maximum total score of 63 points. The standard cutoff scores are as follows: 0-13 total points = minimal depression; 14-19 total points = mild depression; 20-28 total points = moderate depression; and 29-63 total points = severe depression. A reduction in the total score by at least 30% is considered to be clinically significant.
