Abstract:
Bone characterization using Quantitative Ultrasound (QUS) is an attractive alternative to x-ray techniques in cases such as monitoring fracture healing and management of osteoporosis, due to its non-ionizability, portability, and lower cost. Investigated in this paper is the characterization of ultrasonic wave propagation through waveguides with bone-like properties. Physical experiments are performed in a companion thesis on two waveguides: plate and pipe. Simulations designed to recreate these physical experiments are used to provide greater understanding of the results. Both experiments yielded amplitude-time data for equidistant points along the model. Waveform characterization, group velocity, and attenuation rate can be found for each geometry at different frequencies with different material properties. Progress has been made in waveform analysis for ultrasound in bone-mimicking material.
