THEORETIC STUDY ON IMPROVING NONINVASIVE MEASUREMENT ACCURACY OF BLOOD COMPONENT BY DYNAMIC SPECTRUM METHOD
动态光谱法对提高近红外无创血液成份检测精度的理论分析

Utilizing near-infrared spectroscopy for non-invasive blood component concentration sensing has been a focusing topic in biomedical optics applications.But,there is no report about any successful detection techniques that can satisfy the requirements of clinic application(except the blood oxygen). One of the most important difficulties is the effect of the individual discrepancy.Dynamic spectrum(DS) is a new detecting method for blood spectrum developed in recent years.The improvement of accuracy by DS was studied compared with the traditional way here.The errors of traditional NIR non-invasive blood component concentration decision were studied based on the measure theory.Then the way of eliminating these errors by DS was analysed.Our conclusion is that the DS method can improve the accuracy of non-invasive blood component concentration measuring.
