Claim 9:
10. A method of determining where to position a set of electrode elements on a person's head before the set of electrodes is used to apply an alternating electric field to the person's brain, the method comprising:
(a) simulating affixation of a first set of electrode elements to a right side of the person's head at a first plurality of positions, the first set of electrode elements having an upper section positioned above the external opening of the person's right ear canal with an orientation that is predominantly horizontal, and a rear section positioned behind the external opening of the person's right ear canal with an orientation that is predominantly vertical, wherein at least a portion of the rear section of the first set of electrode elements is positioned below the external opening of the person's right ear canal, and wherein at least a portion of the upper section of the first set of electrode elements is positioned in front of the external opening of the person's right ear canal;
(b) simulating affixation of a second set of electrode elements to a left side of the person's head at a second plurality of positions, the second set of electrode elements having an upper section positioned above the external opening of the person's left ear canal with an orientation that is predominantly horizontal, and a rear section positioned behind the external opening of the person's left ear canal with an orientation that is predominantly vertical, wherein at least a portion of the rear section of the second set of electrode elements is positioned below the external opening of the person's left ear canal, and wherein at least a portion of the upper section of the second set of electrode elements is positioned in front of the external opening of the person's left ear canal;
(c) simulating application of an alternating voltage between the first set of electrode elements and the second set of electrode elements at each of the first plurality of positions and at each of the second plurality of positions, respectively;
(d) determining, based on step (c), which of the first plurality of positions and which of the second plurality of positions results in an alternating electric field in the person's brain with high uniformity; and
(e) outputting, based on a result of step (d), a recommended position for the first set of electrode elements and a recommended position for the second set of electrode elements.
