AI Technical Summary

Technical Problem

Current methods for determining transducer locations for generating tumor treating fields are time- and resource-intensive and fail to account for physiological changes in the subject's body, leading to directional variations over time.

Method used

A computer-implemented method that selects pairs of transducer locations on the subject's body by obtaining voltage and current measurements of the induced electric field, calculating resistivity, and selecting recommended locations based on these measurements to optimize transducer placement and improve treatment accuracy.

Benefits of technology

This approach enhances the accuracy and efficiency of tumor treating fields by adapting to physiological changes and providing real-time adjustments for optimal transducer placement, thereby improving treatment effectiveness.

Abstract

A computer-implemented method of determining locations of transducers on a subject's body for applying tumor treating fields, the method including: selecting a plurality of pairs of locations on the subject's body, each pair of locations having a first location to locate a first transducer and a second location to locate a second transducer; obtaining, for each pair of locations, a voltage measurement and a current measurement for an electric field induced between the first transducer and the second transducer, the induced electric field passing through a tumor of the subject's body; calculating, for each pair of locations, a resistivity based on the voltage measurement and the current measurement; and selecting and outputting one or more recommended pairs of locations based on the calculated resistivities.
