Methods, devices, and systems are disclosed for treating patients with ultrasound targeted at regions of the brain. An ultrasound transducer is positioned on a patient's head to target a region of the patient's brain for ultrasound therapy. An ultrasound wave is emitted at the target region of the patient's brain. At least partially concurrently, a fMRI imaging device generates real time images of activity in the patient's brain, for example by ASL protocol, BOLD protocol, or a combination thereof. Activity in the patient's brain caused by the ultrasound wave is detected, typically a distance Δ; from the target region. The transducer is repositioned or reoriented to correct for Δ; and better target the region, and another series of ultrasound waves are directed at the target region with improved accuracy.
