RetinaCAD System
Overview:
Retinal vascular biomarkers can be useful for the early detection and diagnosis of several systemic diseases, such as
- Hypertension
- Diabetes
- Cerebrovascular diseases
- Cardiovascular diseases
RetinaCAD is a computer-aided diagnosis system for fast, reliable and automatic measurement of several retinal biomarkers, namely the Central Retinal Arteriolar Equivalent (CRAE), the Central Retinal Venular Equivalent (CRVE), and the Arteriolar-to-Venular Ratio (AVR) values, as well as several geometrical features associated with vessel bifurcations.
Main Processing Steps:
Image Analysis Tools
- Vessel segmentation tool
- Optic disc localization tool
- Optic disc segmentation tool
- Region of interest tool
- Graph representation tool
- Artery/vein classification tool
- Detection of Normal Images
Measurements
- OD center and OD radius
- CRAE, CRAE, AVR using two different methods
- Vessel features (vessel calibers and angles between vessel segments, …)
- Bifurcation features (angle, bifurcation index, diameter ratio, asymmetry ratio, area ratio, optimality)
Additional Features
- Single click option for the CRAE, CRVE and AVR estimation
- Visualization of intermediate and final results
- Ability to process an individual task
- Display of vessel bifurcation/intersection features using a mouse click
- “Follow-up mouse” tool using a second display window
- Export reports as pdf or Excel files
- Manual editing tools for OD center location, OD radius value, ROI definition and A/V classification
