Table 1.

The percentage of pixels having p-value < 0.05 in the Pearson’s correlation coefficient maps and the delay time between the pulse-oximeter signal and the image data that gave the maximum absolute correlation (second-to-last column). The heart rate for each subject is given in beats per minute in the last column.
