Abstract
When treating a subject using alternating electric fields (e.g., using TTFields to treat a tumor, or using alternating electric fields to increase the permeability of the blood brain barrier), some subjects experience an unpleasant electrosensation effect. This electrosensation can be reduced or eliminated by increasing the area of the transducer arrays that is active during certain times in the treatment. In some embodiments, this is accomplished by applying an AC signal between two pairs of transducer arrays at certain times (as opposed to the prior art approach of applying an AC signal between two individual transducer arrays).
