An embodiment in accordance with the present invention provides a system and method for imaging living tissue and processing laser speckle data anisotropically to calculate laser speckle contrast preferentially along the direction of blood flow. In the present invention, raw laser speckle images are obtained and processed resulting in the anisotropic laser speckle images. The system and method involve the determination of the direction of blood flow for every pixel within the region of interest (primary pixel) and subsequent extraction of a set of secondary pixels in the spatio-temporal neighborhood of the primary pixel that is anisotropic in the direction of blood flow. Speckle contrast is then calculated for every primary pixel as the ratio of standard deviation and mean of all secondary pixels in this anisotropic neighborhood and collectively plotted using a suitable color mapping scheme to obtain an anisotropic laser speckle contrast image of the region of interest.
