Functional Near Infrared Spectroscopy, Multi-channel, Data DisplayAbstract
This article is to introduce a based on functional near infrared spectroscopy (functionalNear - InfraredSpectroscopy, fNIRS) multichannel data show that the software design and development. According to QtDesigner and VisualStudioCode development, it can quickly calculate and analyze the digital signal sent by Teensy board, and carry out data conversion, real-time display waveform. According to the characteristics of near-infrared spectrum divergence in tissues, the light intensity change signal is converted into the change signal of oxygenated hemoglobin and oxygenated hemoglobin concentration according to the modified Lamberbier law, so as to realize the calculation of hemoglobin concentration, and on this basis, the extraction of low-frequency oscillation signal in blood oxygen concentration is completed. Provides a simple and stable software for changes in hemoglobin oxygenation ([HbO]) and reduction ([Hb]) signals and specific low frequency oscillation (sLFOs) data.
