Design of tumor therapy system based on irreversible electroporation

Irreversible electroporation(IRE) based on the high-voltage and steep pulses is a new technique developed in recent years to treat cancer. In this paper, the high-voltage and steep pulses tumor ablation system used the DSP and CPLD as the controller. The pulse output width, pulse frequency, pulse voltage and other parameters can be adjustable. The experimental results show that the system can be operated safely and stably. The output pulse waveform has reached the expected design goal of the system, which is in accordance with the theoretical requirement of irreversible electroporation. At the same time, irreversible electroporation experiments in mice also achieved good results.
