Brief

Initial indirect x-ray imaging tests of a unique 88-mm diameter YAG:Ce single crystal show it has 10 times better resolution than a standard P43 polycrystalline phosphor of the same thickness.

Summary

The provided source does not explicitly state the article's overall purpose. However, it does describe an experiment that was conducted to test a new type of x-ray imaging crystal. The authors, A.H. Lumpkin and A.T. Macrander, tested an 88-mm diameter single crystal YAG:Ce scintillator. They found that the crystal exhibited superior spatial resolution compared to standard polycrystalline phosphors. Specifically, the single crystal had a PSF of 10.5 microns compared to a PSF of 100 microns for the standard polycrystalline phosphors. The authors conclude that the crystal's combined resolution and large area make it suitable for applications in crystal diffraction tests, wafer topography experiments, and biomedical imaging.
