Asset Details

  • Description:
  • The entire process of OCT data processing. First, the initial OCT structure images obtained by the SS‐OCT were registered. Then, 2D angiograms at different locations were obtained by the difference of repeated B‐scans, and the 3D angiograms were reconstructed by Amira software. By comparing the angiograms at baseline and occlusion, the vascular displacement distance can be obtained. The percentage change of VPD was calculated using “locally adaptive region growing algorithm.” On the other hand, by averaging the repeated B‐scans, we were able to obtain average structural images. The influence of confocal characteristics was removed by dividing by the axial PSF proposed by Faber et al. An ODRE method was used to the calculation of OAC. A series of en face OAC maps were obtained by averaging the OACs in the specific depth range. Last, the percentage change of OACs and the edema areas were obtained from the en face OAC map. OAC, optical attenuation coefficient; OCT, optical coherence tomography; ODRE, optimized depth‐resolved estimation; PSF, point spread function; SS‐OCT, swept‐source optical coherence tomography; VPD, vascular perfusion density
