Electric current density imaging of mice tumors

The use of electric current density imaging (CDI) to map spatial distribution of electric currents through tumors is presented, Specifically, a method previously tested on phantoms was implemented in vivo and in vitro for mapping electric current pulses of the same order of magnitude (j congruent to 2500 A/m(2)) as in electrochemotherapy through T50/80 mammary carcinomas, B-16 melanomas and SA-1 sarcomas, A technically simplified method of electric current density imaging is discussed as well, Three geometries of electrodes (flat-flat, point-point, point-flat) indicate altered electric current distribution for the same tumor. This indicates that the method can be used for monitoring the effects of electrochemotherapy as a function of electrode geometry.
