摘要:

光学相干断层扫描(Optical Coherence Tomography,OCT)可在体内提供视网膜各层的高分辨率、3D且非侵入式可视化,是病灶定位和疾病诊断的关键工具。然而,设备成本以及对专业操作人员的需求限制了其广泛应用。相比之下,2D彩色眼底摄影采集速度更快、可及性更高,且对昂贵设备的依赖更少。尽管生成式人工智能已在医学图像合成中展现出良好效果,但由于不同模态之间在数据维度和生物信息方面的固有差异,将2D眼底图像转换为3D OCT图像仍面临独特挑战。为推动眼底到3D OCT生成模型的发展,亚太远程眼科学会(Asia Pacific Tele-Ophthalmology Society,APTOS-2024)组织了题为“基于人工智能从眼底图像生成OCT”的挑战赛。本文详细介绍了该挑战赛框架(称为APTOS-2024 Challenge),内容包括:基准数据集、以两项保真度指标为特色的评估方法——基于图像的距离(像素级OCT B-scan相似性)和基于视频的距离(语义级体积一致性)——以及对表现最佳方案的分析。该挑战赛吸引了342支参赛队伍,收到42份初赛提交,并产生9支决赛队伍。领先方法融合了多方面创新:混合数据预处理或增强(跨模态协作范式)、在外部眼科成像数据集上预训练、集成视觉基础模型,以及模型架构改进。APTOS-2024 Challenge是首个证明眼底到3D OCT合成可行性的基准,可作为改善资源不足医疗环境中眼科护理可及性的潜在解决方案,同时有助于加快医学研究和临床应用。

英文摘要:

Optical Coherence Tomography (OCT) provides high-resolution, 3D, and non-invasive visualization of retinal layers in vivo, serving as a critical tool for lesion localization and disease diagnosis. However, its widespread adoption is limited by equipment costs and the need for specialized operators. In comparison, 2D color fundus photography offers faster acquisition and greater accessibility with less dependence on expensive devices. Although generative artificial intelligence has demonstrated promising results in medical image synthesis, translating 2D fundus images into 3D OCT images presents unique challenges due to inherent differences in data dimensionality and biological information between modalities. To advance generative models in the fundus-to-3D-OCT setting, the Asia Pacific Tele-Ophthalmology Society (APTOS-2024) organized a challenge titled Artificial Intelligence-based OCT Generation from Fundus Images. This paper details the challenge framework (referred to as APTOS-2024 Challenge), including: the benchmark dataset, evaluation methodology featuring two fidelity metrics-image-based distance (pixel-level OCT B-scan similarity) and video-based distance (semantic-level volumetric consistency), and analysis of top-performing solutions. The challenge attracted 342 participating teams, with 42 preliminary submissions and 9 finalists. Leading methodologies incorporated innovations in hybrid data preprocessing or augmentation (cross-modality collaborative paradigms), pre-training on external ophthalmic imaging datasets, integration of vision foundation models, and model architecture improvement. The APTOS-2024 Challenge is the first benchmark demonstrating the feasibility of fundus-to-3D-OCT synthesis as a potential solution for improving ophthalmic care accessibility in under-resourced healthcare settings, while helping to expedite medical research and clinical applications.
