Mojette tomographic reconstruction for micro-CT: a bone and vessels quality evaluation

Abstract : Micro-CT represents a modality where the quality of CT reconstruction is very high thanks to the acquisition properties. The goal of this paper is to challenge our proposed Mojette discrete reconstruction scheme from real micro-CT data. A first study was done to analyze bone image degradations by lowering the number of projections. A second study analyzes trabecular bone and vessels tree through an animal study. Small vessels are filling trabecular holes with almost the same grey levels as the bone. Therefore vessel detectability that can be achieved from the reconstruction algorithm according to the number of projections is a major issue.
