Claim 0:
1. A system for tumor ablation, the system comprising:
a probe comprising:
a first conductor;
a second conductor disposed distal to the first conductor;
an insulator bushing disposed between the first conductor and the second conductor; and
a first thermocouple to measure a temperature at a location on the second conductor;
a second thermocouple on the second conductor;
a third thermocouple on the second conductor; and
a fourth thermocouple on the second conductor;

a generator to produce a current to be conducted between the first conductor and the second conductor to create an ablation region with a first potential ablation perimeter, and wherein the second thermocouple, the third thermocouple, and the fourth thermocouple respectively define a second point along a second potential ablation perimeter, a third point along a third potential ablation perimeter, and a fourth point along a fourth potential ablation perimeter, wherein each of the potential ablation perimeters is different;
a display; and
a processor to:
monitor the temperature at the first thermocouple;
monitor an impedance of the tissue between the first conductor and the second conductor;
control an output of the generator to decrease the current when the impedance increases and to stop the current when a thermal dose reaches a target threshold;
control the output of the generator based on a type of a procedure being performed; and
configure the display to provide a graphical user interface illustrating the first potential ablation perimeter, the second potential ablation perimeter, the third potential ablation perimeter, and the fourth potential ablation perimeter.
