Event & Seminar(Japanease Web Site) Pick up Subject! Multiscale ultrasound tissue characterization Tadashi YAMAGUCHI In general ultrasonic diagnosis, ultrasound waves of several MHz are radiated into the body from the body surface and visualization of ultrasonic information reflected from various tissues (echo) is performed, but its resolution is limitting about 1 mm. In my research, we observed the same living tissue by the frequency from several MHz to hundreds MHz band, and finding the frequency dependency of the intrinsic properties in various tissues in the microstructure below the cells (micro meter scale) and the mixture of multiple tissues (mili meter scale). It can be understand the characteristics of tissue such as moorphology, structure, activity, inflammation, alteration, acoustic characteristics, mechanical properties, etc. with a desired resolution by using an arbitrary frequency band by indexing the property of echo in the macro structure.
