Paper Abstract

Non-invasive measurements of blood velocity at the capillary level are of great interest in many clinical applications. Recently we presented a new method for the quantitative estimation of blood flow velocity, based on the use of the Radon transform. The technique was based on narrow band illumination at 525 nm and tracking of non-uniform distribution of red blood cells within the vessel, rather than the individual blood cells themselves. Here we present a complete error analysis of this useful technique, highlighting the role of camera and illumination choices. Finally we propose in vivo examples on retinal flow imaging and compare the results obtained with this technique to the one proposed by a commercial system.
