3. Complex signal-based optical coherence tomography angiography enables in vivo visualization of choriocapillaris in human choroid
  
  Explore SPIE Digital Library Nov 29 2017 Ophthalmology
  
  The choriocapillaris (CC) plays an essential role in maintaining the normal functions of the human eye. There is increasing interest in the community to develop an imaging technique for visualizing the CC, yet this remains underexplored due to technical limitations. We propose an approach for the visualization of the CC in humans via a complex signal-based optical microangiography (OMAG) algorithm, based on commercially available spectral domain optical coherence tomography (SD-OCT ...

  Explore uspto.gov Jul 11 2017 Ophthalmology , Patents
  
  Abstract Methods for improved acquisition and processing of optical coherence tomography (OCT) angiography data are presented. One embodiment involves improving the acquisition of the data by evaluating the quality of different portions of the data to identify sections having non-uniform acquisition parameters or non-uniformities due to opacities in the eye such as floaters. The identified sections can then be brought to the attention of the user or automatically reacquired. In ...
