Abstract
This application discloses an improved approach for delivering Tumor Treating Fields (TTFields) at a therapeutically effective strength to the infratentorial regions of the brain. A first set of electrode elements is positioned on top of the head and a second set of electrode elements is positioned on the back of the neck. Third and fourth sets of electrode elements are positioned on the lower back right and the lower back left portions of the scalp, respectively. Applying an AC voltage between the first and second sets of electrode elements generates a generally vertical field in the infratentorial regions of the brain; and applying an AC voltage between the third and fourth sets of electrode elements generates a generally horizontal field in those regions.
