Open Biomedical Imaging Archive

The Open Biomedical Imaging Archive (OBIA) is a repository for archiving biomedical imaging and related clinical data in a common DICOM format. OBIA adopts five data objects (Collection, Individual, Study, Series, and Image) for data organization, accepts the submission of biomedical images of multiple modalities, organs, and diseases. In order to protect personal privacy, OBIA has formulated a unified de-identification and quality control process based on the DICOM standard. In addition, OBIA provides friendly and intuitive web interface for data submission, browsing and retrieval, as well as image retrieval. As of November 2024, OBIA has housed data for a total of 991 individuals, 4244 studies, 24,701 series, and 1,946,305 images covering 9 modalities and 30 anatomical sites. Representative imaging modalities are MR, CT, and DX. Anatomical sites include the chest, pelvis, abdomen, head and liver. OBIA offering two types of data accessibility: open access and controlled access. Data access permissions for controlled-access datasets are managed by the submitter. Collectively, OBIA provides a reliable platform for biomedical imaging data management and offers free open access to all publicly available data to support research activities throughout the world.

开放生物医学影像档案（OBIA）是一个用于归档生物医学影像及其相关临床数据，以通用DICOM格式的数据存储库。OBIA采用五类数据对象（集合、个体、研究、序列和图像）进行数据组织，接受多种模态、器官和疾病的生物医学图像提交。为了保护个人隐私，OBIA基于DICOM标准制定了一套统一的去标识化和质量控制流程。此外，OBIA提供了友好且直观的网页界面，用于数据的提交、浏览和检索，以及图像检索。截至2024年11月，OBIA已收录了涵盖9种模态和30个解剖部位的991名个体的数据，4244项研究，24,701个序列和1,946,305张图像。代表性的影像模态包括磁共振成像（MR）、计算机断层扫描（CT）和X射线摄影（DX）。解剖部位包括胸部、盆腔、腹部、头部和肝脏。OBIA提供两种类型的数据访问权限：公开访问和受控访问。受控访问数据集的数据访问权限由提交者管理。总体而言，OBIA为生物医学影像数据管理提供了一个可靠的平台，并向全球的研究活动提供所有公开数据的免费开放访问，以支持全球研究活动。
