The Digital Imaging and Communications in Medicine (DICOM) Standard is a key foundational technology for radiology. However, its complexity creates challenges for information system developers because the current DICOM specification requires human interpretation and is subject to nonstandard implementation. To address this problem, a formally sound and computationally accessible information model of the DICOM Standard was created. The DICOM Standard was modeled as an ontology, a machine-accessible and human-interpretable representation that may be viewed and manipulated by information-modeling tools. The DICOM Ontology includes a real-world model and a DICOM entity model. The real-world model describes patients, studies, images, and other features of medical imaging. The DICOM entity model describes connections between real-world entities and the classes that model the corresponding DICOM information entities. The DICOM Ontology was created to support the Cancer Biomedical Informatics Grid (caBIG) initiative, and it may be extended to encompass the entire DICOM Standard and serve as a foundation of medical imaging systems for research and patient care.
医学数字成像和通信（DICOM）标准是放射学的一项关键基础技术。然而，其复杂性给信息系统开发者带来了挑战，因为当前的 DICOM 规范需要人工解释，并且存在非标准的实现。为了解决这个问题，创建了一个形式正确且计算上可访问的 DICOM 标准信息模型。DICOM 标准被建模为本体，这是一种机器可访问且人类可解释的表示形式，可以通过信息建模工具进行查看和操作。DICOM 本体包括现实世界模型和 DICOM 实体模型。现实世界模型描述了患者、研究、图像和其他医学成像特征。DICOM 实体模型描述了现实世界实体与建模相应 DICOM 信息实体的类之间的连接。创建 DICOM 本体是为了支持癌症生物医学信息网格（caBIG）计划，它可以扩展以包含整个 DICOM 标准，并作为研究和患者护理的医学成像系统的基础。
