AB - X-ray phase contrast (XPC) imaging is an emerging technology that holds great promise for biomedical applications due to its ability to provide information about soft tissue structure *. The need for high spatial resolution at the boundaries of the tissues is noted for this process. Based on results from imaging of relativistic electron beams with single crystals **, we proposed transferring single-crystal imaging technology to this bio-imaging issue. Using a microfocus x-ray tube (17 kVp) and the exchangeable phosphor feature of the camera system, we compared the point spread function (PSF) of the system with the reference P43 phosphor to that with several rare earth garnet single crystals of varying thickness. Based on single Gaussian peak fits to the collimated x-ray images, we observed a four times smaller system PSF (21 microns (FWHM)) with the 25-mm diameter single crystals than with the reference polycrystalline phosphor's 80-micron value. Initial images of 33-micron diameter carbon fibers have also been obtained with small crystals installed. Tests with a full-scale 88-mm diameter single crystal (patent-pending configuration) are being planned.
