Elevated temperatures have been used for many years to combat several diseases including treatment of certain types of cancers/tumors. High Intensity Focused Ultrasound (HIFU) has emerged as a potential non-invasive modality for trackless targeting of deep-seated cancers of human body. For the procedures which require thermal elevation such as hyperthermia and tissue ablation, temperature becomes a parameter of vital importance in order to monitor the treatment on-line. Also, embedding invasive temperature probes for this purpose beats the supremacy of the non-invasive ablating modality. In this paper, we describe the use of a non-invasive and inexpensive conventional imaging ultrasound modality for lesion positioning and estimation of thermal behavior of the tissue on exposure to HIFU. Representative results of our online lesion tracking algorithm for discerning lesioning behavior using image capture, processing and phase-shift measurements are presented.
