説明
Osteoporosis is a skeletal disease which increases the risk of bone fracture. We have proposed a ultrasound technique for the early detection of osteoporosis using two wave phenomenon in cancellous bone. In this phenomenon, we can find the fast wave mainly propagating along trabeculae, and the slow wave propagating in the bone marrow [1]. In the early stage of osteoporosis, the medullary cavity (a hole in the cancellous bone) becomes larger in addition to the decrease of bone volume. The effects of such structural changes seem important to understand two wave phenomenon. In this study, we experimentally studied effects of medullary cavity on the two wave phenomenon.
