抽象的。提出了一种从功能性近红外光谱信号中去除头皮血液信号的实时算法。头皮和深层信号对源-检测器距离有不同的依赖性。利用这一特性来分离这些信号。该算法通过使用动态模型的实验进行了验证，其中浅层和深层吸收独立改变。明确获得了使用两种波长测量氧合和脱氧血红蛋白的算法。该算法对于实时系统可能有用，例如脑机接口和神经反馈系统。
Abstract. A real-time algorithm for removing scalp-blood signals from functional near-infrared spectroscopy signals is proposed. Scalp and deep signals have different dependencies on the source-detector distance. These signals were separated using this characteristic. The algorithm was validated through an experiment using a dynamic phantom in which shallow and deep absorptions were independently changed. The algorithm for measurement of oxygenated and deoxygenated hemoglobins using two wavelengths was explicitly obtained. This algorithm is potentially useful for real-time systems, e.g., brain-computer interfaces and neuro-feedback systems.
