AI Technical Summary
Existing tumor electric field therapy systems cannot simultaneously apply electric fields in different directions to the same target area, resulting in poor treatment effects. Furthermore, traditional treatment methods such as radiotherapy and chemotherapy have side effects.
An insulated electrode system is used, and a periodic control signal is generated by a control signal generator to alternately apply the first and second electric fields in the vertical direction. During the electric field switching process, a segmented voltage boosting and bucking method is used to avoid voltage spikes and ensure that the alternation of electric field directions does not overlap.
It effectively inhibits the proliferation of liver cancer cells, reduces side effects on normal cells, improves treatment efficacy, and avoids voltage spikes caused by electric field overlap.
