A 100-fold full-field X-ray microscope using a Fresnel zone plate (FZP) in combination with a Talbot interferometer for phase tomography was constructed at beamline 37XU, SPring-8 to visualize the morphology of mouse bone specimens with a sub-micron spatial resolution and keeping with 300 μm wide-field of view [1]. However, there was a problem that bone specimens shrunk occasionally due to synchrotron radiation irradiation during CT scans. In this work, a higher-efficiency FZP for 9 keV X-rays has been employed to observe bone samples having soft tissue structures with reduced radiation damage.
