Abstract

The spatial resolution of current near-infrared topography is not enough for clinical application. In this study, the image reconstruction algorithm using prior knowledge about light path length in tissue and spatial frequency in image was proposed and evaluated by simulation. The spatial resolution of topographic image obtained from image reconstruction method is better than that obtained from conventional mapping-interpolation method. The most appropriate image reconstruction method depends on the arrangement of fibres.
