Imaging of tissue reperfusion by dynamic optical tomography

S. Blattman et al. (2000)


We have explored the real–time response of the forearm vasculature to partial obstruction and subsequent restoration of blood flow. Dual–wavelength measurements were collected at 2 Hz, and the resulting image series (120 images per wavelength) was analyzed using appropriate time–series analysis methods. The temporal properties of the absorption coefficients’ spatial distributions gave clear evidence of coordinated reperfusion among well–separated zones of peripheral tissue.
