Deep Brain Stimulator
According to Faraday’s law of induction, changing magnetic fields may cause induced electrical current in conductors within the body.
The gradient magnetic force strength increases away from the isocenter.
On November 22, 2009 we handed Noah off to the MRI staff (for his first MRI since the discovery of his brain tumor) so he could be put to sleep for his scan. After he awoke from the scan, we were questioned about the injury to his arm. The staff quickly realized that he had been somehow burned during his MRI scan.
