| 摘 要： | 我们提出一种高动态光学血管造影成像(HDOA)方法来实现活体生物样本血管造影成像.该方法通过设置高动态范围曝光时间,依据动态积分效应和吸收效应以实现高动态积分时间调制.通过该方法,不仅能够同时获得各级血管清晰的造影图像,还能消除样品厚度不均、吸收系数不同对成像造成的影响.论文以仿体和活体金鱼为样品,通过实验验证了HDOA方法根据动态积分调制效应和吸收效应,能有效实现各级血管同时成像.

| Abstract: | We propose a high-dynamic optical angiography(HDOA) method to obtain blood flow images of a small biological specimen in vivo. High dynamic range exposure time is set to achieve high-dynamic integrated time modulation, which involves dynamic integrated effect and absorption effect. With this method, each-level vessels can be imaged with similar clarity. Moreover, the vessels in locations with different thickness and absorption coefficient can be reconstructed in the same image. Experiments on phantom and in vivo Gold Pristella Tetra were performed to demonstrate that HDOA can achieve each-level vessels imaging based on dynamic integrated effect and absorption effect. |
