Abstract

The multi-channel NIR system can obtain the topographic image of brain function in the cortex. Since the light is strongly scattered in biological tissue, the spatial sensitivity of the source-detector pairs is broadly distributed in the brain cortex. This phenomenon causes poor spatial resolution of topographic imaging. In this study, the spatial sensitivity distribution of the source-detector pairs is incorporated into the reconstruction algorithm of the topographic image to improve the spatial resolution.
