Non-invasive assessment of static scatterer concentration in phantom body fluids using laser speckle contrast analysis technique

Abstract An adequate amount of supply of blood to the body organs is essential for the optimum survival and function of the cells. The Red Blood Cells (RBC) which are the most abundant cells of the blood transports hemoglobin which in turn carries oxygen from the lungs to the tissues. And hence its concentration in blood is an important factor. In this paper, we are presenting LAser Speckle Contrast Analysis (LASCA) as a tool for analyzing RBC concentration. Preliminary results obtained using body fluid such as blood mimicking phantoms are presented here. The technique described provides a non-contact, non-scanning and whole field method for assessing RBC concentration non-invasively.
