4 CONCLUSIONS
Spatial variations in perfusion values from the two
hands of healthy subjects are herein studied from laser
speckle contrast images. We show that the dorsal face
of the two hands in healthy subjects present close
perfusion values (CV < 9.7% for a ROI size of 31
pixels×31 pixels). The possible increase of CV in
diseased states remains to be studied in order to see
whether LSCI could be of interest to improve the di-
agnosis of diseases such as frostbite, Raynaud’s phe-
nomenon, carpal tunnel syndrome, systemic sclerosis,
hand burns, hand flaps or hand wounds.

The authors would like to thank Fredrik Salomonsson
from Perimed for its useful comments regarding the
analysis of the data on white surface.
