Focused Ultrasound

Contact a Navigator

Palm Beach Health Network is the first hospital in the region to offer a new scalpel-free treatment for essential tremor and medication-refractory tremor-dominant Parkinson’s disease. MR-guided focused ultrasound by INSIGHTEC™, uses sound wave energy to treat brain tissue at the source of the tremor. No surgical incision or anesthesia is necessary, and patients may experience immediate and significant reduction in their hand tremors, giving them a chance to get back to their daily activities.

MR-guided focused ultrasound combines two technologies, magnetic resonance imaging (MRI), which pinpoints the exact location in the brain responsible for the tremor, and ultrasound, which precisely delivers over 1,000 highly focused beams of acoustic energy at that exact location without damaging any surrounding brain tissue.


Some of the benefits to this technology include:

  • No surgical incisions resulting in reduced risk of infection.
  • Quicker recovery time with no surgical incision, allowing a return to daily activities within days.
  • Performed as an outpatient procedure – most patients go home within 23 hours.
  • Immediate and significant reduction in hand tremors.
  • Treatment has minimum side effects.

The procedure is performed by Lloyd Zucker, MD, Medical Director of Neurosurgery for Palm Beach Health Network, part of the Palm Beach Health Network. He also serves as Chair of the Department of Surgery at Delray.

Dr. Arif Dalvi works along with Dr. Lloyd Zucker, to bring our community MR-guided focused ultrasound. Dr. Dalvi is the Physician Chief of the Movement Disorders Program at Palm Beach Health Network and is the Director of the Comprehensive Movement Disorders Center at the Palm Beach Neuroscience Institute, part of the Palm Beach Health Network Physician Group.
