AI Technical Summary

Technical Problem

Existing tumor electric field therapy systems cannot simultaneously apply electric fields in different directions to the same target area, resulting in poor treatment effects, and traditional methods have side effects.

Method used

An insulated electrode and an AC signal generator are used. An alternating electric field is generated between the insulated electrodes by alternately applying first and second AC signals. The control signal generator outputs a periodic control signal to ensure that the electric field direction alternates and avoids electric field overlap. A segmented boost and buck method is used to optimize voltage switching, and the electric field directions are arranged perpendicularly.

Benefits of technology

It effectively inhibits tumor cell proliferation, reduces side effects, improves treatment efficacy, and enhances the therapeutic effect on tumor cells.
