title: [Application research of DEI technique based on synchrotron X-ray source in imaging rabbit eyeball in vitro].
abstract: OBJECTIVE
  To study the application of DEI technique in imaging the small structures of rabbit eyeball.
  
  
  METHODS
  DEI technique was used to image the eyeball of New Zealand white rabbit in vitro. The experiments were performed using beamline 4W1A at the topography station of Beijing Synchrotron Radiation Facility (BSRF).
  
  
  RESULTS
  DEI image showed clearly the fine structures of the rabbit eyeball, such as the transparent cornea, the sclera, the ciliaris, and the ciliary body.
  
  
  CONCLUSIONS
  DEI is a new X-ray imaging modality which achieves high contrast and spatial resolution. It also showed obvious effect of edge enhancement. DEI has good potential in observing the micro-structures of eyeballs and other small organs.
