Magnetic Helmet Shrinks Tumor

The tumor's size decreased by nearly a third.

Houston Methodist Neurological Institute researchers shrunk a glioblastoma tumor by 31% over five weeks with a helmet.

The helmet generated an oscillating magnetic field and administered the therapy to a 53-year-old patient. 

Treatment took place in a clinic and at home, began at two hours per day and was increased to up to six hours per day. 

To generate the oscillating magnetic field, permanent magnets rotated in a specific frequency profile and timing pattern. 

The helmet’s design involved three oncoscillators connected to a microprocessor-based electronic controller operated by a rechargeable battery.

The treatment served as the first non-invasive therapy for glioblastoma.

The patient died from an unrelated injury about a month into the treatment.
