Paper Abstract

Mapping of absolute oxygen levels in the brain is critical during stroke and other disorders. One of the standard methods for measuring oxygen tension is through oxygen dependent quenching of phosphorescence. Typically these measurements are limited to a single spatial location due to the need to measure phosphorescence lifetimes. We have developed an instrument to obtain spatial maps oxygen tension in the brain by combining a DMD with phosphorescence lifetime measurements. Blood flow is measured simultaneously with laser speckle contrast imaging. In this paper we describe this instrument and demonstrate its use in studying stroke progression in animal models.
