Enlarge the Field of View of Nano CT in Synchrotron Radiation

Abstract:

nanoCT with synchrotron radiation has a high spatial resolution up to nanoscale which provides an approach to the 3D inter-structure of sample of tiny size in the research of biology, materials and so on. However, due to the high resolution it provide, the field of view is limited to only about 15~60μm. In order to improve the scale of field of view, we discussed a new scan mode called half-scan which is using the symmetry of parallel-beam x-ray and newly applied in the synchrotron radiation imaging field. In this paper, we deduced the data processing method which is consisted of data preprocessing and filter back projection (FBP) algorithm. Numerical simulation and analysis demonstrate that the field of view can be enlarged up to 100% with this method.
