Description
Adrien Lavalley and four colleagues build, in a 2026 study, an air-powered tremor gauge that works inside an MRI scanner during focused ultrasound treatment. Essential tremor therapy aims sound waves at a brain spot, and doctors must verify the aim by watching the tremor fade. Electronic sensors can clash with the scanner's magnets.
Their gauge is a standard breathing cuff held in the patient's hand. Shaking squeezes the cuff, and the pressure pulses travel by tube outside the room to be recorded. Software turns them into a live tremor reading synced with each ultrasound burst. In ten patients, tremor fell by an average of 86 percent right after the test burst, confirming the target in nine. One target was moved after sensory side effects. The authors stress the device's low cost and easy setup.
