Abstract
Systems and methods for automated operation of laser ablation system for disrupting target tissue via heat application are disclosed. The system includes a controller coupled to various devices, such as a magnetic resonance imaging device, a laser energy source, a laser fiber manipulating device, a laser fiber cooling device, and a tissue damage analysis computer system via a communication interface. The controller automatically controls various functions of the coupled devices during a laser ablation procedure while monitoring tissue temperature at a laser ablation site.
