Figure 1From: Effects of some anesthetic agents on skin microcirculation evaluated by laser Doppler perfusion imaging in miceLDPI scan technique. (A) Animal positioning in sternal recumbency on a light-absorbing pad, with the hind plantar surfaces symmetrical and perpendicular to the laser beam. (B) LDPI image post-processing and measurement standardized protocol: the mean intensity of the Doppler signal was registered in ROI encompassing the hind paws and expressed as numerical value normalized for their area (perfusion color scale 0–5 volts).Back to article page
