Abstract The use of Ti-6Al-4V for spinal implants has increased due to its advantageous mechanical properties, biocompatibility, corrosion resistance, and compatibility with MRI procedures. The release of metal ions or particulates, which can result from mechanical loads imposed on the implant, can affect the degree of biocompatibility of spinal implants, possibly influencing their clinical performance. In this project, the titanium metal release from Ti-6Al-4V posterior cervical spine plates was examined using a computational and experimental approach in the canine model.

The tilted beam illumination method is used to improve the resolution comparing with the axial illumination mode. Using this advantage, a restoration method of several tilted beam images covering the full azimuthal range was proposed by Saxton, and experimentally examined. To make this technique more reliable it seems that some practical problems still remain. In this report the restoration was attempted and the problems were considered. In our study, four problems were pointed out for the experiment of the restoration. (1) Accurate beam tilt adjustment to fit the incident beam to the coma-free axis for the symmetrical beam tilting over the full azimuthal range. (2) Accurate measurements of the optical parameters which are necessary to design the restoration filter. Even if the spherical aberration coefficient Cs is known with accuracy and the axial astigmatism is sufficiently compensated, at least the defocus value must be measured. (3) Accurate alignment of the tilt-azimuth series images.
