Application of Discrete Laplace's Equation to Create Topography Map of Near-infrared Spectroscopy Signal

چکیده
Near-infrared spectroscopy (NIRS) enables non-invasive measurement of hemoglobin concentration changes in the cerebral cortex. Creation of a topography map is an important evaluation method used in clinical NIRS studies. In this study, we used Laplace's equation method to create topography maps of NIRS. The method was tested and found to converge very precisely. The method was applied to NIRS signals, and it gave a smooth picture, which did not contradict our physiological knowledge. Finally, a noisy signal was omitted and a topography map was constructed without the information of the corresponding channel, with accurate results.

This review is aimed at celebrating the upcoming 20th anniversary of the birth of human functional near-infrared spectroscopy (fNIRS). After the discovery in 1992 that the functional activation of the human cerebral cortex (due to oxygenation and hemodynamic changes) can be explored by NIRS, human functional brain mapping research has gained a new dimension. fNIRS or optical topography, or near...
