Using Capacitors to Regulate Current in Transducer Arrays for Applying Tumor Treating Fields (TTFields)

Abstract

Transducer arrays for applying alternating electric fields (e.g., tumor treating fields a.k.a. TTFields) to a subject's body typically include a plurality of capacitively coupled electrode elements. Often, certain electrode elements on a given array tend to run hotter than other electrode elements. For example, in many anatomical contexts, the corner elements of the transducer array tend to run hotter than the non-corner elements. The spread of operating temperatures between the electrode elements that tend to run hotter and the other electrode elements can be reduced by wiring a capacitor in series with those electrode elements that tend to run hotter (e.g., the corner elements).
