摘要
Background: Diffraction-enhanced imaging (DEI) is a synchrotron-based x-ray imaging technique that has dramatically improved contrast over standard x-ray imaging techniques. It is possible to acquire images that analyze the x-ray refraction and the apparent absorption (elimination of small-angle scattering) of the object. Methods: Three formalin-fixed porcine eyes were studied at the National Synchrotron Light Source using DEL Conventional absorption-type radiography was conducted for comparison. Results: Conventional absorption radiography did not yield significant detail of the eye anatomy. DEI showed excellent characterization of many ocular structures. The cornea, iris, lens, retina, optic nerve, as well as choroidal vasculature and the ampullae of the vortex veins could all be visualized.
