Effect of skin and subcutaneous tissue on X-ray strain measurement of Ti implant

Abstract

The X-ray diffraction method can be used to measure the lattice strain of crystalline materials. In this study, possibility of strain measurements of implant materials placed in the body was investigated by using the skin and subcutaneous tissue covered Ti materials. Using the characteristic X-rays Mo-Kα, diffracted X-rays from α-Ti could be detected transmit through the skin tissue of 1 mm thickness. Although the X-ray diffraction profile from Ti was detected, this profile included scattered X-rays generated from the skin tissue. The strains of (110) lattice plane of α-Ti specimen under bending deformation was obtained using parallel beam method. The value of strain was almost same between Ti and skin tissue covered Ti.
