The moorO₂Flo-2 perfusion and oxygenation imager is a unique system designed to simultaneously image tissue perfusion and relative tissue oxyhaemoglobin and deoxyhaemoglobin concentration change.

The moorO₂Flo-2 combines Moor Instruments’ existing laser speckle contrast technology for perfusion imaging (moorFLPI-2) with reflectance spectroscopy for oxygenation change imaging.

Non contact imaging.
Blood flow and oxygen videos of any exposed tissue (skin or surgically exposed tissues).
Available in Blood flow only mode with imaging at up to 100 frames per second.
Combined Blood flow and Oxygen at up to 20 frames per second, with each frame containing 1 x blood flow image, 1 x oxyHb image, 1 x deoxyHB image and 1 x colour photograph.
Best spatial resolution of 3.9 microns per pixel to reveal detailed morphology.
10 x optical zoom to image areas from 8mm x 6mm to 300mm x 200mm with motorised zoom and autofocus.
Add multiple “regions of interest” to assess and quantify blood flow and oxygen changes both in real time and post measurement. Area of ROIs calculated automatically.
Colour photo image matches blood flow and oxygen images precisely to aid identification of features
1 camera – 5 parameters.
