Abstract

Mechanical properties of bone, such as density, structural characteristics, and elastic parameters, are related to its biological state. Such properties may be studied by vibration method. In this method, a vibrating force is applied to the bone and the resulting response is recorded and used to evaluate bone properties. The vibration is often induced by mechanical means. Here, we present a vibration method based on the radiation force of ultrasound. Our proposed method is remote and noninvasive. We use this method to monitor changes in bone structure introduced by a partial fracture. The experiments demonstrate that the resonance frequency is an indicative of bone fracture and healing, and the radiation force method can be used as a remote and noninvasive tool for monitoring bone fracture and healing.
