Graduate Student Seminar with Weihao Fan on Diffuse Optical Tomography Using Radio-Frequency Modulated Light

Measurements of dynamic near-infrared (NIR) light attenuation across the human head together with model-based image reconstruction algorithms allow the recovery of three-dimensional spatial brain activation maps. We investigate the potential improvement in reconstructed image quality due to the additional incorporation of phase shift measurements, which reflect the time-of-flight of the measured NIR light, the technique known as frequency domain (FD) fNIRS.
