    Abstract

    Near infrared topographic imaging is an effective instrument to image brain cortex activity. The image is obtained from the changes in light intensity detected with multi-channel source-detcctor pairs. In this study, separation of two absorbers in topographic image is investigated by Monte Carlo simulation to compare the spatial resolution of the double-density arrangement of source- detector pairs with the conventional single-density arrangement. The double density arrangement improves the spatial resolution and accuracy of the position of the absorbers in the topographic image.
