| Research Abstract |
In this study, the variability in ultrasound propagation properties in bone, particularly the properties of "fast and slow waves" which can propagate in cancellous bone, was clarified using finite-difference time-domain (FDTD) simulations with realistic numerical models of cancellous bone, which were constructed from three-dimensional (3D) X-ray microtomographic (μCT) images. Furthermore, an artificial cancellous bone model with a simplified structure for FDTD simulations of the fast and slow wave propagation was developed. These results laid the foundation of a simulation model for ultrasound diagnosis of human bone status.
