Abstract :
The basic reflection properties of fast and slow waves propagating in cancellous bone were numerically investigated using finite-difference time-domain (FDTD) simulations with 18 microcomputed tomographic (μCT) models of bovine cancellous bone. The simulated results showed that both reflection coefficients of the fast and slow waves linearly increased with porosity.
