Outline of Final Research Achievements

We reported the results of HIFU clinical treatments. Pains are alleviated by HIFU therapy in many cases in our clinical trials. Some patients, who couldn't walk, could walk instantly after their treatments. This fact strongly shows the possibility of the HIFU treatments as a main fruit of this research project.
Considering those results, we developed the prototype system of the non-invasive ultrasound pain evaluation and therapeutic system, conducted HIFU irradiation animal experiments, and confirmed the effectiveness of the constructed prototype system. The purpose of this prototype system is to evaluate the HIFU irradiation conditions, such as frequency and amplitude, and the temperature of the tissue, injury of nerves, changes on distribution of the surrounding inflammatory neuropeptide, changes on bone joints.
