The reconstruction images often suffer from artifacts caused by misaligned geometry of flat detector in micro-CT. This paper mainly simulates the causality between the reconstruction image quality and the flat detector geometry by the eight-spheres phantom. The simulation results show that the most influential parameter is β (the rotation angle of the detector plane along the center point O) among...
Full angle noncontact fluorescence molecular tomography allows acquiring large data sets from complete angles, and simplifies the experimental setups. Accurately extracting animal surface is important for this kind of imaging systems. However, in in-vivo experiments, mouse breath movements and mechanical errors will influence the surface reconstruction. An optimal Radon transform based surface reconstruction...
