Abstract

High intensity focused ultrasound (HIFU) is a non-invasive method by which ultrasound can be used to thermally ablate tissue. One important application is the treatment of tumors. However, real-time imaging of the heating of tissue and lesion formation is a major barrier for HIFU. Our research involves employing a multi-modal approach, based on ultrasound imaging system, by which temperature distribution and the presence of a lesion can be determined. Methods we plan to use include classical backscatter, ultrasound tomography, acousto-optic imaging and elastography. By combining acoustical, optical and mechanical properties of the lesion we anticipate developing a robust approach to tracking HIFU lesion formation in real time.
