CONTROL AND DELIVERY OF ELECTRIC FIELDS VIA AN ELECTRODE ARRAY

摘要

A method of controlling electric fields created by a plurality of electrodes. The method includes repetitively applying multiple sets of voltages to at least some of a plurality of electrodes over a treatment period to achieve and maintain a target temperature, the at least some of the electrodes being treatment electrodes. The sets of voltages may be in patterns such that a unique current pattern between electrodes is created for each set of voltages, resulting in temperature averaging. The voltage at each electrode may be determined based on a temperature of an adjacent electrode. The voltage at each electrode may also or alternatively be determined based on an estimated voltage at the electrode.

1. A method of controlling electric fields created by a plurality of electrodes, comprising:
repetitively applying multiple sets of voltages to at least some of a plurality of electrodes over a treatment period so as to heat a target tissue to a selected temperature or temperature range, the at least some of the electrodes being treatment electrodes, and the multiple sets of voltages including: a first set of voltages that creates an electric potential difference between at least some adjacent pairs of the treatment electrodes; and a second set of voltages that creates an electric potential difference between at least some adjacent pairs of the treatment electrodes for which an electric potential difference was not created while applying the first set of voltages, wherein the multiple sets of voltages in combination create an electric potential difference between each adjacent pair of treatment electrodes.
