| Research Abstract |
We have been developing see-through brain observation display for NIRS(Near Infrared Spectroscopy) measurement. It reconstructed the stereoscopic images from the MRI(Magnetic Resonance Imaging) DICOM(Digital Imaging and Communication in Medicine) data of the T2 method. These images displayed on 7.1-inch liquid crystal display to left and right eye. As a result of verifying for 50 subjects, the stereoscopic vision of the brain was possible to all people, and it was possible to observe hemodynamics of the cerebral cortex during a task with body movement. Then, we proposed a separation method for the optical pathlength influence by the variance plot and the variogram analysis using the variance of the sample mean to NIRS(Near-infrared Spectroscopy) time series signal. As a validation example, we conducted the variance plot and the variogram analysis on slightly cerebral activation tasks by 10 subjects of normal adult males.
