Quantification of Bone Remodeling in SR mu CT Images of Implants

Abstract

For quantification of bone remodeling around implants; we combine information obtained by two modalities: 2D histological sections imaged in light microscope and 3D synchrotron radiation-based computed microtomography, SR mu CT. In this paper, we present a method for segmenting SR mu CT Volumes. The impact of shading artifact at the implant interface is reduced by modeling the artifact. The segmentation is followed by quantitative analysis. To facilitate comparison with existing results, the quantification is performed on a, registered 2D slice from the volume, which corresponds to a histological section from the same sample. The quantification involves measurements of bone area, and bone; implant contact percentages.We compare the results obtained by the proposed method on the SR mu CT data with manual measurements on the histological sections and discuss the advantages of including SR mu CT data in the analysis.
