Modeling and monitoring of blood perfusion in burn skin has been presented in this study. A non invasive Laser speckle contrast imaging (LSCI) system is presented here for monitoring different flow conditions in a burn layer simulated capillary phantom. Speckle contrast variations with respect to changes in burn depth and blood perfusion rate have been studied in this work. © 2011 Springer-Verlag.

Laser Speckle Contrast Imaging for Perfusion Monitoring in Burn Tissue Phantoms

IFMBE Proceedings

Measuring microcirculatory tissue blood perfusion is of interest for both clinicians and researchers in a wide range of applications and can provide essential information of the progress of treatment of certain diseases which causes either an increased or decreased blood flow. Diabetic ulcer associated with alterations in tissue blood flow is the most common cause of non-traumatic lower extremity amputations. A technique which can detect the onset of ulcer and provide essential information on the progress of the treatment of ulcer would be of great help to the clinicians. A noninvasive, noncontact and whole field laser speckle contrast imaging (LSCI) technique has been described in this paper which is used to assess the changes in blood flow in diabetic ulcer affected areas of the foot. The blood flow assessment at the wound site can provide critical information on the efficiency and progress of the treatment given to the diabetic ulcer subjects. The technique may also potentially fulfill a significant need in diabetic foot ulcer screening and management. © 2014 SPIE.
