Abstract

Ultrasound technology offering a safer and inexpensive method compared to X-ray densitometry to evaluate bone quality in order to predict fracture cause by osteoporosis disease. Yet, dual X-ray absorptiometry still become choice due to its accuracy and reliability to predict fracture risk compared to quantitative ultrasound (QUS). Moreover, QUS method also isn't fully exploiting interactions between ultrasound wave and bone structure orientation. Hence, this paper is focused on investigation of fast and slow wave propagation in cancellous bone by manipulating vertical (y) and horizontal (x) direction of bone structure orientation. Using Finite Difference Time Domain simulation software, 50 Volt peak-to-peak of the Sine Gaussian wave is transmitted through cancellous bone model as well as setting up other parameter. The result shows that, at the y-direction, first and second wave which have similar behavior with fast and slow wave was observed in time domain at the earlier of wave arrival. The results also have a good agreement with other research where fast and slow wave can be clearly observed in time domain depending on cancellous bone orientation. Besides, future study will focus on analysis of fast and slow wave in overall backscattered wave using Pulse Echo measurement technique.
