Abstract
Perfusion measurement method. The method includes detecting a signal emanating from the tissue and processing the signal to detect fluctuations substantially spatially correlated on a length scale less than 1 centimeter. The fluctuations are then analyzed to obtain a measure of perfusion. In one embodiment, the detected fluctuations are substantially correlated with fluctuations of a biological parameter such as the cardiac cycle or the respiratory cycle.
