| Research Abstract |
Basic researches have performed to realize a new, precise and safe ultrasonic evaluation system of bone. Making use of the detailed information of ultrasonic waves which passed through different parts of bone, the effects of anisotropic structure, elasticity and mineral crystallites orientation on the ultrasonic wave properties were evaluated quantitatively. These data will become very important for the in vivo evaluation of bone using the new ultrasonic system. The other important achievement, the simulation of wave propagation in bone, is a strong assistance technology to help actual construction of the new system.
