DICOM StudyInstanceUID对患者而言应该是唯一的吗? [英] Should a DICOM StudyInstanceUID be unique to the patient?

问题描述

在处理DICOM研究，系列和媒体概念时，我想知道这些值在所有数据中是唯一的，还是仅对它们所属的患者而言是唯一的.

While working with the DICOM study, series and media concepts, I wondered if these values are to be unique over all data, or only to the patient they belong to.

换句话说；我可以让2个患者的研究/系列/样本实例uid对两个患者使用相同的值吗?

Phrased otherwise; can I have 2 patients having a study/series/sop instance uid that is the same value for both patients?

还是DICOM标准根本不关心这一点，实现者可以自行决定吗?

Or does the DICOM standard simply doesn't care about that and is that open to the implementor to decide?

推荐答案

在DICOM中，研究(由研究实例UID标识)始终与单个患者相关联.有关详细信息，请参见DICOM标准第3部分.

In DICOM, a Study (identified by its Study Instance UID) is always associated with a single Patient. See DICOM standard part 3 for details.

要回答您最初的问题/想法:唯一标识符(UID)必须是全球唯一的，即在所有患者，设备，医院等世界范围内都是唯一的.

To answer your initial question/thought: a Unique Identifier (UID) has to be globally unique, i.e. world-wide over all patients, devices, hospitals, etc.
