A method and system is provided to induce mild hypothermia in a patient through controlled heating of the preoptic anterior hypothalamus (POAH) in conjunction with cooling of patient's body. The system employs an ultrasound transducer that may be positioned extracorporeally to a patient skull for emitting ultrasound energy to the POAH.
