Abstract

This chapter present a set of studies that have been developed with the goal of probing the possibilities of using laser speckle effect as a tool to extract macrocirculatory hemodynamic parameters. Within this project, a laser speckle prototype has been constructed and three bench experiment have been designed. The first bench experiment consists on using multi-wavelength light sources to extract the vibration frequency of a phantom and heart rate of several subjects. The second experiment consists on the extraction of the pulse pressure waveform using the same instrumentation and processing algorithms as the ones used on microcirculation laser speckle imaging. Finally, a pilot study was also designed in order to use laser speckle for 2D image segmentation. The obtained results revealed that laser speckle has the capability to extract macrocirculatory hemodynamic parameters and that this feature can be included in commercially available devices. In this sense, the ability to extract macrocirculatory and microcirculatory parameters could lead to interesting commercial advantages.
