| The Doppler signal is linearly proportional to perfusion of the upper 200–300 μm of the skin[131]. Tissue perfusion is quantified in regions of interest (ROI) defined in the limbs relative to the contralateral, non-ligated side and can be displayed as color-coded images[132]. Perfusion measurements obtained from ROIs of thighs are confounded by fur, skin pigmentation and motion artifacts from the abdomen and have been shown not to correlate with limb perfusion[132]. We therefore take LDI measurements from the feet, which correlate with other measures of limb perfusion[18, 133].
