Arrays for Providing Tumor Treatment Fields with Selectively Addressable Sub-Elements

摘要

Tumor treatment fields (TTFields) can be delivered to the subject's body at higher field strengths by turning off one or more overheated electrode elements without turning off other unheated electrode elements. This may be accomplished using a plurality of temperature sensors, each temperature sensor being arranged to sense a temperature at a respective electrode element; It includes a plurality of electrically controlled switches, each of which is wired to switch on or off a current to an individual electrode element. The controller receives a signal from the temperature sensor to determine the temperature of each electrode element, and controls the control input state of each electrically controlled switch to selectively cut off the current in the overheated electrode element or to set the duty cycle in all electrode elements. Adjust.
