Abstract

Tumor treating fields (TTFields) can be delivered by implanting a plurality of sets of implantable electrode elements within a person's body. Temperature sensors positioned to measure the temperature at the electrode elements are also implanted, along with a circuit that collects temperature measurements from the temperature sensors. In some embodiments, an AC voltage generator configured to apply an AC voltage across the plurality of sets of electrode elements is also implanted within the person's body.
