Quantitative ultrasound is a useful tool for bone quality assessment because ultrasound reflects the elastic property of bone, patients are not exposed to radiation, and because the cost of the measurement system is low. Bone tissue is made of cortical bone (solid structure) and cancellous bone (porous structure); therefore, it is necessary to relate the received waveform to the complex bone structure. A time domain analysis was carried out in order to understand the behaviors of the two-wave separation by modelling the wave propagating mode, and the analysis using wavelet transform and instantaneous frequency of the received data. Because these techniques may be useful not only for bone diagnosis but also other fields handling time-domain signals, we introduce our approaches of signal analysis methods. |
