Two wave propagation image for investigating the anisotropic structure of cancellous bone

摘要

Two-wave phenomenon in cancellous bone has been reported by several investigators. Making use of this phenomenon, a new QUS device has been introduced to evaluate the radius in vivo. We have also reported that two waves reflect not only bone mass but also the complex bone structure of cancellous bone. We then propose a new simple imaging technique based on the two-wave phenomenon for investigating the anisotropic structure.
