Displacement versus time (panel (a)), cross-correlation coefficient (CC) versus time (panel (b)), 1st derivative of CC versus time (panel (c)) and 2nd derivative of CC versus time (panel (d)) for representative signals arising from luminal blood (blue), extravasated blood (red) and soft tissue (green). Soft tissue is shown to exhibit smaller displacement, CC, 1st derivative of CC and 2nd derivative of CC variance than luminal and extravasated blood. Soft tissue is also shown to exhibit higher mean CC.
