Attenuation-refraction-scattering computed tomographic experimental system with a conventional X-ray tube: System optimization & image fusion

A classic-optics-based grating-based attenuation-refraction-scattering radiographic & computed tomographic experimental system with a conventional X-ray tube has been built to synchronously reconstruct the distributions of the linear attenuation coefficient, refractive index gradient and generalized scattering parameter of a tested sample in only one computed tomographic scanning process. System optimization and a fusion method of three kinds of images are presented to show desirable structures of the sample. Some preliminary experimental results proved that our system can obtain most comprehensive physical characteristics of the sample.
