Claim 13:
14. An apparatus for imposing electric fields through a target region in a body of a patient, the apparatus comprising:
at least one transducer array having a plurality of electrode elements configured for placement on the body of the patient, the electrode elements configured to provide TTFields via an alternating current waveform;
a first conductor, a second conductor and a third conductor,
a sensor array having a plurality of temperature sensors, the first conductor, the second conductor and the third conductor, the first conductor, second conductor and third conductor each connected to two or more of the plurality of temperature sensors, a first temperature of the sensor array connected to the first conductor and the second conductor, a second temperature sensor connected to the first conductor and the third conductor; and,
a controller configured to:
provide a first known amount of electricity for activation of the first temperature sensor via the first conductor and the second conductor and to provide a second known amount of electricity for activation of the second temperature sensor via the first conductor and the third conductor;
obtain a first electrical reading induced by the first known amount of electricity and a second electrical reading induced by the second known amount of electricity; and,
determine a first temperature reading based on the first electrical reading and a second temperature reading based on the second electrical reading; and

wherein the alternating current waveform is adjusted based on the first temperature reading and the second temperature reading.
