Two-wave behavior under various conditions of transition area from cancellous bone to cortical bone. The two-wave phenomenon, the wave separation of a single ultrasonic pulse in cancellous bone, is expected to be a useful tool for the diagnosis of osteoporosis. However, because actual bone has a complicated structure, precise studies on the effect of transition conditions between cortical and cancellous parts are required. This study investigated how the transition condition influenced the two-wave generation using three-dimensional X-ray CT images of an equine radius and a three-dimensional simulation technique. As a result, any changes in the boundary between cortical part and trabecular pa...
A waveguide-based acoustic microscope. A new instrument is presented which is capable of high resolution acoustic imaging at relatively low frequencies. This approach results in increased complexity of the signal processing required and reduced throughput of the instrument. However, these disadvantages are amply compensated by the ability to create velocity scan images of materials with either high attenuation or low material velocities. These measurements are not possible using traditional/acoustic microscopes. The initial performance of the new instrument is demonstrated using thin samples of shim materials to show that acceptabl...
