High-speed laser speckle contrast imaging and its applications in neurovascular research. (Invited Paper)

11 April 2024 • 10:50 - 11:20 CEST | Etoile B, Niveau/Level 1

Abstract

We will discuss the theoretical and practical foundations and limitations of high-speed laser speckle contrast imaging and demonstrate some of its applications in neurovascular research. Specifically, we will answer how short exposure time affects the contrast analysis, what camera and the speckle-to-pixel size ratio to use and how to analyse the data. We will present the first results on the pulse wave propagation imaging in the brain of awake and anaesthetised ageing (from 18 to 81 weeks) mice and, finally, discuss the translational perspectives and related image design.

Dmitry D. Postnov is an associate professor at Aarhus University, Denmark, working primarily with dynamic light scattering techniques and their application to characterise brain blood flow and metabolism. He holds PhD in cardiovascular physiology (awarded in 2016 by the University of Copenhagen, Denmark) and MSc degree in medical physics (2012, Saratov State University, Russia). In 2016, Dr. Postnov received a grant from the Novo-Nordisk Foundation to join the leading neurophotonics imaging group at Boston University led by Prof. David Boas. After returning to Denmark, Dr Postnov received support from the Lundbeck Foundation in 2020 and, most recently, from the Independent Research Fund Denmark to establish the blood flow imaging lab at Aarhus University. Dmitry Postnov is primarily known for his contributions to Laser Speckle Contrast Imaging research and the development of Dynamic Light Scattering Imaging (DOI:10.1126/sciadv.abc4628).
