使用自行研制的推帚式显微高光谱成像系统采集了正常、白血病人血液涂片的显微高光谱图像数据。通过对正常、白血病人血液显微高光谱数据进行处理,获得了人血液的单波段图像,并提取了部分血液细胞的典型透射率光谱曲线。分析这些曲线发现,病变细胞透射率普遍高于正常细胞,特别是在541.3nm附近透射率高出了50%左右。通过对血液涂片的图像和光谱特征进行分析表明,经过一定的改进,可以将显微高光谱成像系统作为一种新的检测手段,辅助医学研究人员对人血液进行分析。

A pushbroom microscopic hyperspectral imaging device was developed to study the normal and leukemic blood cells of human. The microscopic hyperspectral images of blood from normal and leukemic human were collected and processed. Some typical transmitted spectrum curves of blood cells were extracted and analyzed. The results show that the transmittances of leukaemia blood cells are 50 percent higher than those of the normal at 541.3 nm. From the images and spectrums of the blood,it can be seen that the microscopic hyperspectral imaging device can be used to study the changes of spectrum characters and physical chemistry composition of the human blood.
