Bone is a composite medium organized into a complex hierarchical structure. Several research groups worldwide have applied ultrasonic techniques to investigate experimentally and numerically the structure of bone at different hierarchical levels. The advance in imaging modalities such as micro-computed tomography and scanning acoustic microscopy in combination with the use of robust computational tools has led to the development of realistic computational models of long bones. The ultrasonic assessment of bone microstructure and fracture healing using computational techniques can provide insight into complicated wave propagation effects which cannot be evaluated using traditional experimental procedures. This paper presents the milestone studies in the domain of ultrasonic evaluation of bone diseases such as osteoporosis and bone healing using numerical methods. The results indicate the significant diagnostic and monitoring role of quantitative ultrasound.
