Abstract

We demonstrate the simultaneous mapping of haemoglobin oxygenation and blood flow changes of human skin and the exposed cortex in rats by broad-band reflectometry and laser speckle contrast analysis (LASCA). A hard- and software set-up is realized with a high temporal resolution achieved by techniques of multi- and manycore computing. Spatial and temporal resolved changes of haemoglobin oxygenation and blood flow in rats are observed in response to middle cerebral artery occlusion and cortical spreading depression.
