Thermal ablation techniques, such as ohmic heating, high-intensity
ultrasonic heating, and other temperature-based methods, have shown promise in
effectively destroying tumor tissues. However, their widespread adoption has
been hindered due to the potential for collateral damage to neighboring healthy
tissues. On the other hand, instant temperature measurement in and around the
target area during thermal therapy will facilitate the application of such treatments.
One method that can be used for temperature measurement in tissues is the
pulse-echo method based on the variation of the flight time in the ultrasound
signals returning from the target area. In this study, an agar phantom,
prepared as a tissue-mimicking material, was heated homogeneously and by
monitoring US waves in it, the temperature changes were measured with
thermocouples. As a result, the signals obtained from the phantom were
processed and the results pointed out that the change in flight time can be
used to determine temperature change in the phantom.
