Abstract(in English) Attention has come to be paid to diagnosis of osteoporosis using ultrasonic reflection method. Symptom of osteoporosis appears in cancellous bone. The cancellous bone has the structure of three layers consist of soft tissues and cortical bones. The harmless ultrasonic equipment enable to diagnose patients every day and is useful to obtain the stage of illness. We made a phantom having three layers of concentric circles and researched about the reflected wave analysis in both simulation and experiment. As a result, we obtained that the characteristic of the reflected pulses was affected by the acoustic impedance and attenuation of the media. It is confirmed validity of the method.
