The use of diagnostic ultrasound as a tool for two-dimensional noninvasive temperature imaging is described. The mathematical and physical principles behind this new approach are given. It is shown that temperature changes on the order of 0.1 °C can be detected with a spatial resolution on the order of 1 mm. It is further shown that temperature variations can be tracked up to nearly 20 °C from baseline for relatively long durations. The advantages and limitations of this new temperature imaging method are discussed. Its application to guidance and control of thermal surgery is discussed and illustrated with examples.
