Abstract
The blood flow velocity optical monitoring techniques, such as laser speckle velocimetry, are attractive due its noninvasive character, but they are limited to superficial blood vessels. The visualization of deep blood vessel is difficult because of the highly scattering coefficient of the biological tissue. There are some techniques that allow the visualization of deep blood vessels, for example: optical clearing, Magnetomotive Laser Speckle Imaging and Pulsed Photo-Thermal Radiometry, unfortunately these techniques use an external agent to improve the visualization of blood vessels. In this work we improve the visualization and location of in-vitro deep blood vessels by speckle image processing without an external agents. The proposed methodology is based in a homogeneity measurement of the co-occurrence matrix by the direct processing of the speckle image. Our technique is able to determine the edges of a deep blood vessel and therefore improves its visualization.
