| Outline of Final Research Achievements |
Feasibility of MR thermometry of the joints using thermal shift of the water proton resonance frequency was confirmed in an animal model. However, reproducibility in human body was poor. Then, Non-Invasive measurement of temperature distributions during hyperthermia treatments using ultrasound B-mode images was investigated. Feasibility of this method was confirmed inside the agar phantom and animal joints. Microwave diathermy utilized in daily medical practice was able to heat the area about 2.5cm from the skin and this diathermy could not increase the temperature of deep area. The heating method using a resonant cavity applicator was developed to heat the deep tissues inside the joints.
