REAL-TIME ULTRASOUND MONITORING OF HEAT-INDUCED TISSUE INTERACTIONS

摘要

The present invention includes an apparatus, method and system for monitoring and controlling radiation therapy, the system including a radiative source that emits energy that enters a tissue and is absorbed at or a near a target site in the tissue to heat the tissue; an ultrasound transmitter directed at the target site, wherein the ultrasound transmitter emits ultrasound signals to the tissue that has been heated by the radiative source; an ultrasound receiver directed at the target site, wherein the ultrasound receiver receives ultrasound signals emitted from the ultrasound transmitter and reflected from the tissue that has been heated by the radiative source; and a signal processor that processes the received ultrasound signal to calculate a tissue composition scan or tissue temperature scan.
