The microcirculatory correlator probe has been used on multiple occasions on the abdominal viscera and clear pulse-wave tracings have been obtained from all the intra-abdominal organs. There is a linear correlation between deflection of pulse-wave and intestine blood flow in an isolated loop of intestine under low flow conditions. The probe has been used in two circumstances to good clinical advantage.

Diffuse optical measurement is an evolving optical modality providing a fast and portable solution for microcirculation assessment. Diffuse optics in static and dynamic modalities are combined here in a system to assess hemodynamics in skin tissues of control and diabetic subjects. The in-house developed system consists of a laser source, fiber optic probe, a low-cost avalanche photodiode, a finite element model (FEM) derived static optical property estimator, and a software correlator for continuous flow monitoring through microvasculature.
