📝 摘要(中文)
近年来,生物医学图像分析的进展主要受到Segment Anything Model (SAM)的推动。该技术最初为通用计算机视觉开发,现已迅速应用于医学图像处理。SAM的核心在于其无需先验知识即可对图像中的对象进行分割或识别,适应性强,能够根据指定的分辨率或关注区域调整分割。本文回顾了2023年4月至9月期间的相关研究,分析了SAM在解决临床挑战中的应用,尽管在某些特定领域仍存在不足,如颈动脉、肾上腺、视神经和下颌骨的分割。我们探讨了SAM的创新技术及其在多样化医学成像场景中的有效应用。
🔬 方法详解
问题定义:本文旨在解决生物医学图像分割中的对象识别问题,现有方法在特定解剖结构的分割上存在局限性,难以适应多样化的临床需求。
核心思路:论文的核心思路是利用SAM的零-shot学习能力,允许模型在没有先验知识的情况下进行图像分割,增强其在医学图像处理中的适用性。
技术框架:整体架构包括数据预处理、模型训练和后处理三个主要阶段。数据预处理阶段负责图像标准化,模型训练阶段利用SAM进行分割,后处理阶段则优化分割结果以提高准确性。
关键创新:最重要的技术创新在于SAM的适应性分割能力,能够根据不同的分辨率和关注区域进行调整,这与传统方法的固定分割策略形成鲜明对比。
关键设计:在参数设置上,SAM采用了动态调整的损失函数和多层卷积网络结构,以提高分割精度和模型的泛化能力。

📄 摘要(原文)
Recent advancements in biomedical image analysis have been significantly driven by the Segment Anything Model (SAM). This transformative technology, originally developed for general-purpose computer vision, has found rapid application in medical image processing. Within the last year, marked by over 100 publications, SAM has demonstrated its prowess in zero-shot learning adaptations for medical imaging. The fundamental premise of SAM lies in its capability to segment or identify objects in images without prior knowledge of the object type or imaging modality. This approach aligns well with tasks achievable by the human visual system, though its application in non-biological vision contexts remains more theoretically challenging. A notable feature of SAM is its ability to adjust segmentation according to a specified resolution scale or area of interest, akin to semantic priming. This adaptability has spurred a wave of creativity and innovation in applying SAM to medical imaging. Our review focuses on the period from April 1, 2023, to September 30, 2023, a critical first six months post-initial publication. We examine the adaptations and integrations of SAM necessary to address longstanding clinical challenges, particularly in the context of 33 open datasets covered in our analysis. While SAM approaches or achieves state-of-the-art performance in numerous applications, it falls short in certain areas, such as segmentation of the carotid artery, adrenal glands, optic nerve, and mandible bone. Our survey delves into the innovative techniques where SAM's foundational approach excels and explores the core concepts in translating and applying these models effectively in diverse medical imaging scenarios.
