Abstract
Irreversible electroporation (IRE) is a focal ablation therapy that uses high voltage, short electrical pulses to destroy tumor tissue. The success of treatment directly depends on exposure of the entire tumor to a lethal electric field magnitude. However, this exposure is difficult to predict ahead of time and it is challenging for clinicians to determine optimal treatment parameters. One method clinicians rely upon for the cessation of pulse delivery is to monitor the resistance value of the tissue, as the cells within the tissue will undergo changes during electroporation. This work presents a computational model which incorporates human pancreatic tumor conductivity, and compares predicted and measured output currents from IRE treatments of human patients. The measured currents vary widely from patient to patient, suggesting there may areas of high local conductivity in the treatment area.
