Simulation and in vivo investigation of light-emitting diode, near infrared Gaussian beam profiles
M. Mirbagheri, Naser Hakimi, E. Ebrahimzadeh, S. Setarehdan Near infrared spectroscopy is an optical imaging technique which offers a non-invasive, portable, and low-cost method for continuously measuring the oxygenation of tissues. In particular, it can provide the brain activation through measuring the blood oxygenation and blood volume in the cortex. Understanding and then improving the …
