Orthogonal polarization spectral imaging - A new clinical method for monitoring of microcirculation ["Orthogonal polarization spectral imaging": Eine neue klinische methode für das monitoring der mikrozirkulation]

The orthogonal polarization spectral (OPS) imaging technology is a new non-invasive method to directly visualize multiple conditions of the microcirculation which has several clinical applications in humans. Quantitative measurement of the diameter of vessels, the velocity of red blood cells and functional capillary density (FCD) can be made. Activation of leukocytes can be monitored and also quantified. A transdermal approach can be used in premature babies and neonates to view the microcirculation and has also been used experimentally to determine haemoglobin levels. The application to various surfaces and solid organs allows a variety of pathophysiologies and phases to be examined.
