Automatic pairing of electrode assemblies that are used to apply tumor treating fields (ttfields) to a subject’s body based on responses to signals that are sent into the electrode assemblies

Abstract

Alternating electric fields (e.g., TTFields) can be imposed in a subject’s body using a set of electrode assemblies. Each of the electrode assemblies is connected to a switch array by a respective cable. The system sends signals into these cables (e.g., signals that cause LEDs mounted on the electrode assemblies to light up) and observes the effects of sending the signals (e.g., observing which LED lights up). Based on the observation, the system determines which of the electrode assemblies are positioned on opposite sides of a region of interest in the subject’s body. The system can then configure the switch array to apply an AC voltage across those electrode assemblies to induce TTFields in the subject body.
