The purpose of this study is to establish the imaging of trabecular archtecture of cancellous bone using ultorasonics because the imaging of architecture allows strong information to diagnose osteoporosis. We obtained the amplitude A-mode signal from medical ultrasonic scanner and distinguished between trabecular bone and bone marrow. This distinction is based on dumping curve, which is named threshold line made from the top points of the amplitude A-mode signal. The image of ceramic specimen and real cancellous bone of cattle femur were made applying the method of imaging proposed here. This imaging may improve the reproducibility and be useful in osteoporosis.
