Query: First Point-Spread Function and X-Ray Phase-Contrast Imaging Results
  With an 88-mm Diameter Single Crystal   In this study, we report initial demonstrations of the use of single crystals
in indirect x-ray imaging with a benchtop implementation of propagation-based
(PB) x-ray phase contrast imaging. Based on single Gaussian peak fits to the
x-ray images, we observed a four times smaller system point-spread function
(PSF) with the 50-{\mu}m thick single crystal scintillators than with the
reference polycrystalline phosphor/scintillator. Fiber-optic plate
depth-of-focus and Al reflective-coating aspects are also elucidated. Guided by
the results from the 25-mm diameter crystal samples, we report additionally the
first results with a unique 88-mm diameter single crystal bonded to a fiber
optic plate and coupled to the large format CCD. Both PSF and x-ray phase
contrast imaging data are quantified and presented.
