Ultrasound waves due to their inherent small wavelength can be used in diagnosis or evaluation of tissue. Ultrasound simulations can be useful to investigate and analyze different properties at different sites especially when there is no volumetric data available. In the proposed paper, simulation of ultrasound in a 2-D bone model and hardware implementation has been presented. Due to complex structures of bone, a simple linear model consisting of both cortical and cancellous bone has been proposed. In the simulation, a broadband emitter with center frequency of 1 Megahertz is used along with an array of receivers to capture the signal. An attempt has been made to calculate bone density parameters in-vivo for human feet, and finally display the computed parameters onto a LCD using Arduino Uno Board. An algorithm involving fourier transforms was used to calculate Broadband Ultrasound Attenuation (BUA) and Speed of Sound (SoS) in Matrix Laboratory (MATLAB).
