摘要
本文搭建了一套光声谱技术检测系统,进行血红蛋白含量的基础实验研究。结果证明,光声技术是活体血红蛋白含量无损检测中潜在的有效工具,可精确测量深度为6mm高散射介质下的血红细胞含量的变化。
In this study, noninvasive measurement of concentration of hemoglobin has been investigated by using photoacoustic method. We detailedly report a home-made photoacoustic experiment system for this study. The photoacoustic signals, generated by varying the hemoglobin concentration in blood experimentally, were picked up and analyzed. The results show that the photoacoustic technique is a useful and helpful tool for noninvasive monitoring of the total hemoglobin concentration in-vivo, for it can accurately detect the variation of the total hemoglobin concentration of hemoglobin, even when the blood vessel is deep in high scattering medium for 6mm.
