- Аннотация: Purpose: The intracranial three-dimensional (3D) visualization of the whole volume of the eyeball at micrometric resolution has not been achieved yet either in clinical nor in preclinical diagnostic research. Overcoming this limitation may provide a new tool for clinical and preclinical studies of different pathologies of the various sections of the eye. The aim of this work is to give the first insight of a volumetric visualization at the high resolution of the entire enucleated and intracranial postmortem rabbit eyeballs.Methods: X-ray computed tomography phase-contrast imaging was used to obtain 3D models of enucleated and intracranial rabbit eyes. Images were compared with the ones measured by using optical coherence tomography (OCT) images. The experiment was carried out at the European Synchrotron Radiation Facility.Results: Combining the unique possibilities offered by phase-contrast imaging, microtomography, and the properties of synchrotron radiation, the 3D visualization of the whole eyeball, at an isotropic voxel size of 3.1 μm3, is reported here for the first time.Conclusions: High image contrast is achieved without the necessity of injection of contrast agents, thanks to the superior performances, achieved by x-ray phase-contrast imaging with respect to the conventional radiographic imaging. The measurement protocol developed within this work opens the way for in vivo high-resolution visualization of the entire organ.
