Abstract

A method for determining a location of a transducer on a subject's body for applying tumor treating fields. The method comprises determining a near-surface portion of a tumor in the subject's body, the near-surface portion of the tumor closer to a surface of the subject's body than other portions of the tumor; determining a near-tumor position on the subject's body, the near-tumor position on the subject's body closer to the near-surface portion of the tumor than other positions of the subject's body; determining an outer perimeter of the transducer, the transducer comprising a plurality of electrode elements electrically coupled to each other, the plurality of electrode elements of the transducer being located within the outer perimeter; and identifying a portion of the outer perimeter of the transducer to be located substantially at the near-tumor position on the subject's body.
