In preparation for treatment, your head will be cleanly shaven. This is necessary to so that the focused ultrasound beams have a clear path through the skull and to avoid the chances of getting a scalp burn. You will be given a local numbing medication and a standard stereotactic frame will be secured to your head, to keep you from moving during the treatment.
You may have a urinary catheter placed to drain your bladder during the treatment. Your heart rate, blood pressure and blood oxygen levels will be monitored throughout the procedure. You may be given medication to keep you comfortable. You will lie on the treatment bed which will move in and out of the MRI scanner in the MRI room. You will be conscious, communicating with the physician and nurses in the MRI control room, throughout the treatment.
