System for planning tumor-treating electric fields based on temperature control and absorbed energy in body and system for performing electric field therapy including the same

Abstract

Provided is a system for planning tumor-treating electric fields based on temperature control and absorbed energy in body, comprising a setting unit initially setting the number of electrodes, an electrode location, a duration and strength of voltage for each; a calculating unit calculating absorbed dose and temperature distribution in the body based on the initial settings; an evaluating unit evaluating the calculated absorbed dose and temperature distribution in the body to determine if they meet a preset reference; a changing unit changing at least one of the number of electrodes, the electrode location, the duration or strength of voltage for each electrode when the preset reference is not met; and a planning unit deriving an optimal electric field treatment plan by performing an optimization process including repeating the calculation, the determination and the changing steps until the dose distribution and temperature distribution in the body meet the preset reference.
