【Abstract】 A new laser instrument for direct noninvasive measurement of regional tissue microcirculation blood flow is reported.The theory based on the laser Doppler principle and the light beating spectroscopy is discussed. The instrument is evaluated using a fluid model. A unique and linear relationship between the instrument response and flux of red cells is demonstrated. The new instrument is used to measure blood flow of tissue surface microcirculation in the laboratory as well as at the bedside.更多还原
