Abstract
When Tumor Treating Fields (TTFields) are applied to a subject's brain through the subject's skull, the skull dramatically attenuates the amplitude of the TTFields. The attenuating effect of the skull can be surmounted by making small through-holes in the skull, and installing individual electrodes in each of those through-holes so that the inner ends of those individual electrodes are positioned beneath the subject's skull. Then, when an AC voltage is applied between the electrodes on one side of the subject skull and the electrodes on the opposite side of the subject's skull, the resulting electric field will not pass through the skull and will therefore not be attenuated.
