Phase Analysis of Low Frequency Hemodynamic Oscillations in Near Infrared Spectroscopy.Zheng, Feng.
Abstract: To study low frequency oscillations (around 0.1 Hz) of tissue, oxy-hemoglobin and deoxy-hemoglobin concentrations measured by near-infrared spectroscopy, we proposed two phase analysis methods: one is a cross-correlation phasor method, and another is a phase synchronization analysis method. Both methods yield similar results and provide a straightforward visualization of the phase relati... read more
