Outline of Final Research Achievements

In this study, an ultrasound-guided non-invasive hyperthermia system using a resonant cavity was developed. Specifically, we developed a non-contact resonant cavity applicator using the ultrasound image device to find the position and size of the heated target. After achieving our original goal, we examined the possibility of measuring temperature distributions using ultrasound images. It was found that non-invasive 2-D temperature distributions were measured from the displacement of ultrasound images before and after heating.
