Imaging cerebral blood flow through the intact rat skull with temporal laser speckle imaging

Opt Lett. 2006 Jun 15;31(12):1824-6. doi: 10.1364/ol.31.001824.

Abstract

We discovered that laser speckle temporal contrast analysis (LSTCA) is able to access the two-dimensional (2D) cerebral blood flow velocity and vessel structure through the intact rat skull. It is demonstrated that LSTCA can significantly suppress the influence of the laser speckle from the stationary structure, such as the skull, and thus reveal the blood flow and morphology of blood vessels through the laser speckle images recorded from the intact rat skull.
