The Cancer Imaging Archive

The Cancer Imaging Archive (TCIA) is a service which de-identifies and hosts medical images of cancer for public download. 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. DICOM is the primary file format used by TCIA for radiology imaging. Supporting data related to the images such as patient outcomes, treatment details, genomics and expert analyses are also provided when available.

癌症影像档案库（The Cancer Imaging Archive, TCIA）是一项对癌症医学影像进行去标识化处理并托管以供公众下载的服务。该数据集以"合集（collection）"为单位进行组织，通常依据共同患有的疾病类型（如肺癌）、影像模态或类型（如磁共振成像（Magnetic Resonance Imaging, MRI）、计算机断层扫描（Computed Tomography, CT）、数字组织病理学等）或研究主题对患者影像数据进行归类。数字成像与通信医学（Digital Imaging and Communications in Medicine, DICOM）是TCIA用于放射学影像的主要文件格式。若有相关可用数据，系统还会提供与影像相关的配套辅助数据，包括患者转归情况、治疗细节、基因组学数据以及专家分析结果等。
