Abstract
A method and system for using real time closed loop feedback to control the delivery of heat energy is disclosed herein. An energy delivery system may be used to deliver heat energy to a target to effect a change in the target. For example, medical professionals use laser energy to irreversibly damage cells found in cancerous tumors without damaging the surrounding healthy cells. The energy delivery system includes a temperature detection system, a data processor, and a heat generating device. The temperature detection system obtains temperature data from a target and transmits the data to the data processor. The data processor may process the temperature data to provide real time feedback control to the heat generating system, as well as display the data as one or more images on a graphical user interface. The heat generating system receives control commands from the data processor and modulates its heat output accordingly.
