Abstract
An apparatus and method for determining a volume of tissue mass destroyed. The present invention includes a temperature probe and a laser probe having a temperature sensor. The laser probe and temperature probe are inserted to measure a temperature of the tissue mass and a temperature of tissue mass surrounding the tissue mass. By determining the volume of tissue mass destroyed, a graphical representation of the volume of tissue mass destroyed is provided whereby real-time visual monitoring of the destruction of the tissue mass is achieved.
