RadGenome/RadGenome-ChestCT
收藏资源简介:
RadGenome Chest CT数据集是一个基于CT-RATE的全面、大规模、区域指导的3D胸部CT解读数据集。该数据集扩展了原始数据集,包含了25,692个非对比3D胸部CT体积和来自20,000名患者的报告。数据集特点包括:197个类别的器官级别分割掩码,提供了解读的中间视觉线索;665 K个多粒度关联报告,每个报告句子与CT体积的对应解剖区域相关联;1.3 M个关联VQA对,问题和答案都与参考分割掩码相关联,使模型能够将视觉证据与文本解释相结合。验证集中的所有关联报告和VQA对都经过了人工验证以确保数据集质量。该数据集旨在推动多模态医疗基础模型的发展。
RadGenome Chest CT is a comprehensive, large-scale, region-guided 3D chest CT interpretation dataset based on CT-RATE. The dataset extends the original dataset to include 25,692 non-contrast 3D chest CT volumes and reports from 20,000 patients. Features of the dataset include: organ-level segmentation masks for 197 categories, providing intermediate visual clues for interpretation; 665 K multi-granularity grounded reports, with each sentence of the report linked to the corresponding anatomical region of the CT volume; 1.3 M grounded VQA pairs, where questions and answers are all linked with reference segmentation masks, enabling models to associate visual evidence with textual explanations. All grounded reports and VQA pairs in the validation set have undergone manual verification to ensure dataset quality. The dataset is intended to advance the development of multimodal medical foundation models.
