“…This in turn becomes a lengthy and tedious task for processing the images for results. In order to support the performance of this task, a new algorithm such as motion history image (MHI) [9,10] has already been proposed. It has been applied to a variety of LSCI data to visualize the regions where perfusion changes occur [9,10].…”

“…One of the limitations was that it provides information on perfusion variations only [10]. It was not possible to differentiate between high and low perfusion values using the MHI method [10]. In order to overcome these limitations, in the present study we propose and validate the use of MHI algorithm to the dynamic fluorescent imaging (DF) data to visualize the hypoperfusion (decreased blood flow) during an acute cerebral ischemic event.…”

Abstract. BACKGROUND:We use a temporal template method, the motion history image (MHI), to visualize the hypoperfusion (decreased blood flow) during an acute cerebral ischemic event in a mouse brain. The MHI method was implemented on the dynamic fluorescent (DF) data images. AIMS: Our aim was to implement the MHI method on the DF imaging data and visualize the regions where perfusion evolves with time. METHODOLOGY: The MHI method was used to process the DF data images recorded during an acute cerebral ischemic event in a mouse brain. RESULTS: We demonstrate that, the MHI images clearly illustrates the locations where perfusion decreases during occlusion and that is more easily obtained in comparison to a visual inspection of all of the raw DF images constituting the recordings. CONCLUSION: MHI can be a useful tool for the clinical and research studies.

Dynamic light scattering (DLS) is a well known experimental approach uniquely suited for the characterization of small particles undergoing Brownian motion in randomly inhomogeneous turbid scattering medium, including water suspension, polymers in solutions, cells cultures, and so on. DLS is based on the illuminating of turbid medium with a coherent laser light and further analyzes the intensity fluctuations caused by the motion of the scattering particles. The DLS‐based spin‐off derivative techniques, such laser Doppler flowmetry (LDF), diffusing wave spectroscopy (DWS), laser speckle contrast imaging (LSCI), and Doppler optical coherence tomography (DOCT), are exploited widely for non‐invasive imaging of blood flow in brain, skin, muscles, and other biological tissues. The recent advancements in the DLS‐based imaging technologies in frame of their application for brain blood flow monitoring, skin perfusion measurements, and non‐invasive blood micro‐circulation characterization are overviewed. The fundamentals, breakthrough potential, and practical findings revealed by DLS‐based blood flow imaging studies, including the limitations and challenges of the approach such as movement artifacts, non‐ergodicity, and overcoming high scattering properties of studied medium, are also discussed. It is concluded that continued research and further technological advancements in DLS‐based imaging will pave the way for new exciting developments and insights into blood flow diagnostic imaging.
