Magnetic Resonance Knife

Non-Invasive Brain Treatment Without Skull Opening

Revolutionary technology transforming tremor and epilepsy treatment history

Magnetic Resonance Knife

What is the Magnetic Resonance Knife?

MRgFUS (Magnetic Resonance-guided Focused Ultrasound) is a groundbreaking non-invasive treatment system. Doctors use MRI as a "see-through eye" to precisely locate abnormal neural nuclei deep within the brain.

Thousands of ultrasound transducers in the equipment helmet emit low-intensity ultrasound waves that penetrate the scalp and skull, converging at the predetermined target. The tissue at the focal point rapidly heats to 55°C-80°C, causing precise coagulative necrosis (ablation).

Key Advantages

Significant advantages over traditional craniotomy or electrode implantation

No Craniotomy Needed

No surgical incision, no general anesthesia required. Dramatically reduces infection and bleeding risks. Ideal for elderly or high-risk patients.

Real-Time Monitoring

MRI real-time temperature monitoring allows doctors to strictly control ablation range and temperature like GPS navigation.

Rapid Recovery

Entire procedure takes only 2-3 hours. Patients remain awake throughout and can even chat with doctors. Most discharged same day.

Treatment Indications

Currently FDA and NMPA approved for the following conditions

FDA & NMPA Approved

Essential Tremor & Parkinson's Tremor

For patients who couldn't hold a water cup or write before treatment, tremor symptoms can be significantly relieved after the procedure. Many patients see improvement immediately after a single treatment.

FDA & NMPA Approved

Refractory Epilepsy

For drug-resistant epilepsy (such as hypothalamic hamartoma), traditional surgical resection carries extremely high risks. MRgFUS can achieve non-invasive precise ablation for eligible patients, significantly reducing or stopping seizures.

Clinical Research

Psychiatric Disorders

Beyond movement disorders, MRgFUS shows potential in treating depression, OCD, and anxiety disorders. For patients unresponsive to conventional medication and psychological intervention, precise regulation of emotional circuits can yield unexpected therapeutic effects.

Why Choose MRgFUS?

  • Immediate Symptom Improvement

    Many patients can observe symptom improvement immediately after a single treatment session

  • Minimal Side Effects

    No general anesthesia complications, no implant foreign body reactions

  • Outpatient Procedure

    Most patients discharged the same day with quick return to normal activities

Future Applications

  • Refractory Neuropathic Pain

    Providing new hope for patients with chronic pain conditions

  • Alzheimer's Disease Research

    Exploring potential applications in neurodegenerative disease treatment
