Optical Coherence Tomography Angiography (OCTA) has been increasingly used in the management of eye and systemic diseases in recent years. Manual or automatic analysis of blood vessel in 2D OCTA images (en face angiograms) is commonly used in clinical practice, however it may lose rich 3D spatial distribution information of blood vessels or capillaries that are useful for clinical decision-making. In this paper, we introduce a novel 3D vessel reconstruction framework based on the estimation of vessel depth maps from OCTA images. First, we design a network with structural constraints to predict the depth of blood vessels in OCTA images. In order to promote the accuracy of the predicted depth map at both the overall structure- and pixel- level, we combine MSE and SSIM loss as the training loss function. Finally, the 3D vessel reconstruction is achieved by utilizing the estimated depth map and 2D vessel segmentation results. Experimental results demonstrate that our method is effective in the depth prediction and 3D vessel reconstruction for OCTA images.% results may be used to guide subsequent vascular analysis

虽然已经有越来越多的研究使用深度学习技术从2D en face OCTA中提取血管结构,但对于这种方法,已知在曲线结构(如视网膜血管系统)上的数据注释过程非常昂贵和耗时,尽管很少有人尝试解决注释问题。在这项工作中,我们提出了应用基于涂鸦的弱监督学习方法来自动化像素级注释。所提出的方法称为OCTAve,它将弱监督学习与对抗性和新颖的自监督深度监督相结合,使用涂鸦注释的地面实况增强。我们的新机制被设计为利用来自UNet类架构的鉴别层的鉴别输出,其中聚合鉴别输出和分割图谓词之间的Kullback-Liebler分歧在训练期间被最小化。实验结果表明,这种组合方法可以更好地定位血管结构。我们在大型公共数据集上验证了我们提出的方法,即,玫瑰,OCTA-500。的分割性能进行比较,对两个国家的最先进的全监督和基于涂鸦的弱监督的方法。我们在实验中使用的工作的实现位于[LINK]。
