Abstract
When electrodes are used to impose an electric field in target tissue within an anatomic volume (e.g., to apply TTFields to treat a tumor), the position of the electrodes can be optimized by generating a 3D map of electrical conductivity or resistivity of the anatomic volume. A location of the target tissue within the anatomic volume is identified, and a dipole is added to the 3D map at a location that corresponds to the target tissue. positions for the electrodes that maximize a potential attributable to the dipole are determined based on the 3D map of electrical conductivity or resistivity and the location of the dipole.
