Fundamental Study of Bone-Mimicking Phantom Using Apatite

Because of the success of the ultrasonic method for diagnosing osteoporosis, the challenge to obtain ultrasonic images of the inner part of bone has begun. Since ultrasonic imaging of the inner part of bone is very difficult, further research is necessary. The goal of this study is to develop a bone-mimicking phantom for use in the visualization of bone by ultrasound. The developed phantom using apatite and polyvinyl alcohol (PVA) as materials with consideration of the periosteum showed fairly good agreement with real bone.
