OCT Angiography
This optional software module allows the visualization of the microvasculature of the retina. Both blood flow and structural visualiza-tion give additional diagnostic information about many retinal diseases. Angiography scan allows assessment of the structural vasculature of the macula, the periphery or the optic disc. Extremely short scanning times of 1,6 seconds in standard resolution or 3 seconds in high resolution.
Now Angiography OCT can become a routine in your diagnostic practice.
 
ANGIO ANALYISIS METHODS

QUANTIFICATION
The quantification tool provides quantification of the vasculature in the whole analyzed area together with values in specific zones and sectors. Thanks to the heat map of the analyzed vasculature the evaluation of vascular structure conditions is much faster. The choice of the quantification method increases the sensitivity of analyses for specific deseases.

Available quantification methods:

• Vessel Area Density - it is defined as the total area of perfused vasculature per unit area in a region of measurement.
• Skeleton Area Density - it is defined as the total area of skeletonized vasculature per unit area in a region of measurement.

 
Quantification is available for a specific layer in Angio OCT exam:

• Retina: Superficial Plexus and Deep Plexus
• Disc: RPC - Radial Peripapillary Capillary

ANGIO-ANALYTICAL TOOLS
FAZ – Foveal Avascular Zone measurements enable the quantification and monitoring of changes in Superficial and Deep vascular layers. The FAZ tool is also available for narrow and wide scans.

	FAZ Area [mm2] Perimeter [mm] Circularity

VFA – Vascular Flow Area allows the user to examine the pathologically affected area and to precisely measure the area covered by vascularization.
The simple and easy area measurement can be performed on a predefined or user-selected vascular layer.

	Area [mm2] Flow Area [mm2]

NFA – Non Flow Area measurement tool makes it possible to quantify the Non Flow Area on the OCT Angio examination. It provides the sum of all marked areas.

ANGIO MOSAIC
The Angiography mosaic delivers high-detailed images over large field of the retina.
Advanced tab provides: view of any vascular layers, enface view of vascular layers, depth coded and thickness map. Mosaic modes: 10x6 mm, 12x5 mm, 7x7 mm, 10x10 mm and Manual (up to 12 images).
Manual mode allows to scan the desired region.Built-in analytics allow to see vascular layers, enface or thick-ness maps.
