Efficient data extraction method for near-infrared spectroscopy (NIRS) systems with high spatial and temporal resolution.
IEEE Trans. Biomed. Circuits and Systems（2013）
摘要
An hardware-efficient method for the extraction of hemodynamic responses in near-infrared spectroscopy systems is proposed to increase the spatial and temporal resolution. The performance improvement is attributed to high signal-to-noise ratio receivers, a modulation scheme, and a multi-input-multi-output based data extraction algorithm. The proposed system shows more than twofold improvement in the figure of merit compared to conventional designs. Experimental results support the validity of the proposed system.
