AI Technical Summary

Technical Problem

Existing tumor treatment field (TTField) applications are limited to specific body regions and do not effectively treat tumors on the torso, such as the chest and abdomen, due to the need for multiple transducer pairs and potential skin irritation from prolonged use.

Method used

A method involving the use of four transducers positioned on the torso and thighs, alternating electric fields, and repositioning to reduce discomfort, along with a system for determining optimal transducer locations based on thermal removal potential.

Benefits of technology

Effectively delivers TTFields to the torso with reduced skin irritation and discomfort, ensuring therapeutic efficacy by maintaining electric field intensity within the torso region.

Abstract

A method of applying a tumor treatment field to the torso of a subject's body, the method including the steps of positioning a first transducer at a first location on the subject's body, the first location being on the torso of the subject's body; positioning a second transducer at a second location on the subject's body, the second location being below the torso of the subject's body; and inducing an electric field between at least a portion of the first transducer and at least a portion of the second transducer.
