摘要:

视网膜内液体或囊肿是黄斑病变的重要症状之一,其在OCT图像中有效地可视化。这些异常的自动分割在医学图像处理研究中已经被广泛研究。在本文中,我们提出了一种新的基于U-Net的方法,用于不同供应商的视网膜内囊肿分割,改善了以前基于深度的技术所面临的一些挑战。该方法分为两个主要步骤:1-先验信息嵌入和输入数据调整,2- IRC分割模型。在第一步中,我们将信息注入网络,以克服网络在接收数据和学习重要上下文知识方面的一些限制。在下一步中,我们在标准U-Net架构的编码器和解码器部分之间引入了一个连接模块,该模块可以更有效地将信息从编码器传输到解码器部分。两个公共数据集,即OPTIMA和KERMANY的评估所提出的方法。结果表明,该方法是一种有效的供应商无关的IRC分割方法,平均Dice值为0.78和0.81的OPTIMA和KERMANY数据集,分别。

英文摘要:

Intra retinal fluids or Cysts are one of the important symptoms of macular pathologies that are efficiently visualized in OCT images. Automatic segmentation of these abnormalities has been widely investigated in medical image processing studies. In this paper, we propose a new U-Net-based approach for Intra retinal cyst segmentation across different vendors that improves some of the challenges faced by previous deep-based techniques. The proposed method has two main steps: 1- prior information embedding and input data adjustment, and 2- IRC segmentation model. In the first step, we inject the information into the network in a way that overcomes some of the network limitations in receiving data and learning important contextual knowledge. And in the next step, we introduced a connection module between encoder and decoder parts of the standard U-Net architecture that transfers information more effectively from the encoder to the decoder part. Two public datasets namely OPTIMA and KERMANY were employed to evaluate the proposed method. Results showed that the proposed method is an efficient vendor-independent approach for IRC segmentation with mean Dice values of 0.78 and 0.81 on the OPTIMA and KERMANY datasets, respectively.
