Ultrasonic techniques for assessment of temperature and thermal damage

Research output: Contribution to journalConference articlepeer-review


The use of diagnostic ultrasound as a tool for noninvasive temperature feedback, image guidance, and damage assessment is described. The physical principles allowing for such applications are discussed along with the underlying scattering models. 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. In addition to temperature feedback, the potential for using ultrasound for damage assessment is discussed. Finally, the latest efforts on new self-guided ultrasonic phased array systems for imaging and therapy are discussed. The paper is concluded with a discussion of the future directions that will ultimately define the role of diagnostic and therapeutic ultrasound in the general area of image-guided surgery.
