Abstract

We developed a reflectance continuous-wave near-infrared spectroscopy topography system with multi-source and multi-detector sensor head. A single wavelength (808 nm) laser diode is used as the original light source. With different-measurement approach, we can reconstruct images representing the variety of cerebral blood volume in clinical applications. Phantom experiments have been taken to verify the performance of the system. We also took clinical experiments for brain activities research during acupunctures and have obtained some primarily results
