| Research Abstract |
A multimodal system for the brain-function measurement using near-infrared light is investigated to improve the spatial resolution and accuracy of brain-function images. The novel algorithm for image reconstruction using a virtual head phantom is proposed. The 3D-structure of the virtual head phantom is based upon MRI scan of an adult head. The proposed system is evaluated by simulations using the virtual head phantom and experiments. The brain-function images measured by the system using double-density probe arrangement are effectively improved by the image reconstruction algorithm using the virtual phantom.
