Retina vessel quantification

 

 

Purpose

To quantifying the vasculature in macular OCTA images.

 

Input

En face projection of OCT-A scans from commercial and homebuilt OCT systems (.jpg/.png./tiff/.bmp)

User defined reginal masks (optional)

Adjustable segmentation parameters

 

Output

Vessel segmentation, binary skeleton and binary flow impairment zone map

Vessel area density, vessel diameter, vessel skeleton density and vessel complexity index of whole image and reginal masks

 

Validation

US patent US10354378B2
