1. A method of delivering tumor-treating electric fields to a body of a patient, comprising:
receiving a scan of the body of the patient;
identifying at least two tumor-filled areas on the scan, each tumor-filled area having at least one tumor therein;
determining a spatial relationship between the at least two tumor-filled areas;
arranging an array of insulated electrode elements on the body of the patient, the array of insulated electrode elements being coupled to an electric field generator, a control device being configured to send a signal to the electric field generator causing the electric field generator to deliver tumor-treating electric fields to the insulated electrode elements;
determining at least two subarray firing configurations for the array of insulated electrode elements for targeting the at least two tumor-filled areas, the at least two subarray firing configurations depending at least in part upon the spatial relationship between the at least two tumor-filled areas; and
delivering the tumor-treating fields to the at least two tumor-filled areas of the patient using the at least two subarray firing configurations.
