Abstract

Bone has been studied at the microscopic level by borrowing from industry ultrasonic technology for nondestructive materials inspection. This technology has been realized in the form of scanning acoustic microscopy (SAM), which permits visualization of material elastic properties. SAM measures acoustic impedance, which has been shown to be related to the elastic stiffness coefficient C33 of orthotropic materials. By the use of ultrasonic frequencies, high resolution images are created. These images demonstrate for inhomogeneous materials the degrees of variations in elastic properties as a function of position. In previous experiments, the in vivo loading conditions and strain distributions of the metatarsal were determined by strain gage and finite element analysis. The present experiment concerns the use of SAM to measure the elastic properties of the bone around the implants.
