The Cancer Imaging Archive

TCIA is a service which de-identifies and publishes medical images of cancer for download. New data proposals are reviewed by an Advisory Group on a quarterly basis. The data are organized as “collections”; typically patients’ imaging related by a common disease (e.g. lung cancer), image modality or type (MRI, CT, digital histopathology, etc) or research focus. Supporting data related to the images such as patient outcomes, treatment details, genomics and expert analyses are also provided when available. The user community are also encouraged to publish new analyses derived from TCIA datasets. Examples include adding new image labels, annotations, organ/tumor segmentations, and radiomic/pathomic features to existing collections.

TCIA（肿瘤图像共享数据库）是一项提供去标识化并公开发布癌症医学图像供下载的服务。新的数据提案将每季度由咨询小组进行审查。数据以“集合”的形式组织；通常包括与共同疾病（如肺癌）、图像模态或类型（MRI、CT、数字病理学等）或研究焦点相关的患者影像。当可用时，还提供了与图像相关的支持数据，例如患者预后、治疗细节、基因组学以及专家分析。同时，鼓励用户社区基于TCIA数据集发布新的分析，例如向现有集合中添加新的图像标签、注释、器官/肿瘤分割以及放射组学/病理组学特征。
