Abstract

We report on the first three dimensional tomographic localization of vascular reactivity in the brain. Using a model-based iterative image reconstruction algorithm we show the spatial distribution of changes in the absorption coefficient caused by changes in blood volume. Unlike currently available topographic reconstruction techniques, three-dimensional, volumetric reconstruction schemes promise to be capable of spatially distinguishing between signals originating in the cerebral cortex from those originating in the overlying tissues.
