Biological Imaging by X-ray Phase Tomography Using Diffraction-Enhanced Imaging

Abstract

A feasibility test of phase tomography using diffraction-enhanced imaging (DEI) was performed with biological tissues consisting of not only soft tissues but also cartilages and bones. Reconstructed three-dimensional images indicated that phase tomography using DEI has an advantage from a biological viewpoint over phase tomography using a crystal X-ray interferometer, which cannot be applied to samples involving marked refractive index changes at boundaries between soft tissues and bones or cartilages.
