DICOM（Digital Imaging and Communications in Medicine）即医学数字成像和通信，是医学图像和相关信息的国际标准（ISO 12052）。它定义了质量能满足临床需要的可用于数据交换的医学图像格式。 [1]
DICOM 被广泛应用于放射医疗，心血管成像以及放射诊疗诊断设备（X射线，CT，核磁共振，超声等），并且在眼科和牙科等其它医学领域得到越来越深入广泛的应用。在数以万计的在用医学成像设备中，DICOM 是部署最为广泛的医疗信息标准之一。当前大约有百亿级符合 DICOM 标准的医学图像用于临床使用。
自从 1985 年 DICOM 标准第一版发布以来，DICOM 给放射学实践带来了革命性的改变，X 光胶片被全数字化的工作流程所代替。就像 Internet 成为信息传播应用的全新平台，DICOM 使“改变临床医学面貌”的高级医学图像应用成为可能。比如在急诊科中，心脏负荷测试，乳腺癌的检查，DICOM 为医生和病人服务，是医学成像有效工作的标准。
