1.1 本规程涵盖了计算机射线照相（CR）成像和数据采集设备的互操作性，具体规定了常用术语中的图像数据传输和档案存储方法。本规程旨在与《规程》结合使用 E2339 关于无损评估中的数字成像和通信（DICONDE）。实践 E2339 定义了NEMA PS3的工业适应性 / ISO 12052（DICOM，请参阅http://medical.nema.org)，图像数据采集、审查、存储和档案存储的国际标准。 实践的目标 E2339 通常称为DICONDE，旨在提供一种标准，以便于在符合DICONDE标准的任何系统上显示和分析无损检测结果。为此，练习 E2339 提供了适用于所有无损检测模态的数据字典和一组信息模块。此练习是对练习的补充 E2339 通过提供计算机射线照相测试方法特有的信息对象定义、信息模块和数据字典。 1.2 制定此实践是为了克服在使用专有数据传输和存储方法分析或归档CR测试设备的数据时出现的问题。 随着数字技术的发展，数据必须通过使用开放的、全行业的数据传输和档案存储方法来保持可破译性。该实践定义了一种方法，在该方法中，所有标准CR技术参数和测试结果都以标准方式进行通信和存储，而不考虑数字技术的变化。 1.3 本规程未规定: 1.3.1 评估实施是否符合标准的测试或验证程序。 1.3.2 声明一致性的设备上标准的任何功能的实现细节。 1.3.3 通过集成一组设备（每个设备都声称符合DICONDE）实现的系统所期望的一整套特征和功能。 1.4 尽管此实践不包含需要单位的值，但它确实描述了存储和通信数据的方法，这些方法确实需要正确解释单位。本规程要求的国际单位制应视为标准单位。本规程中不包括其他计量单位。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。 本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ===意义和用途====== 5.1 负责创建、传输和存储计算机射线照相无损检测数据的人员将使用此做法。本规程将定义一组信息模块，这些模块与本规程一起 E2339 DICOM标准将提供组织CR检查数据的标准手段。CR检查数据可以在符合标准的任何设备上显示和分析。希望查看按照规程存储的任何CR检查数据的人员 E2339 可以使用这种做法来帮助他们解码和显示包含在符合DICONDE的检查记录中的数据。

1.1 This practice covers the interoperability of computed radiography (CR) imaging and data acquisition equipment by specifying image data transfer and archival storage methods in commonly accepted terms. This practice is intended to be used in conjunction with Practice E2339 on Digital Imaging and Communication in Nondestructive Evaluation (DICONDE). Practice E2339 defines an industrial adaptation of NEMA PS3 / ISO 12052 (DICOM, see http://medical.nema.org), an international standard for image data acquisition, review, storage, and archival storage. The goal of Practice E2339 , commonly referred to as DICONDE, is to provide a standard that facilitates the display and analysis of NDE results on any system conforming to the DICONDE standard. Toward that end, Practice E2339 provides a data dictionary and a set of information modules that are applicable to all NDE modalities. This practice supplements Practice E2339 by providing information object definitions, information modules and a data dictionary that are specific to computed radiography test methods. 1.2 This practice has been developed to overcome the issues that arise when analyzing or archiving data from CR test equipment using proprietary data transfer and storage methods. As digital technologies evolve, data must remain decipherable through the use of open, industry-wide methods for data transfer and archival storage. This practice defines a method where all standard CR technique parameters and test results are communicated and stored in a standard manner regardless of changes in digital technology. 1.3 This practice does not specify: 1.3.1 A testing or validation procedure to assess an implementation's conformance to the standard. 1.3.2 The implementation details of any features of the standard on a device claiming conformance. 1.3.3 The overall set of features and functions to be expected from a system implemented by integrating a group of devices each claiming DICONDE conformance. 1.4 Although this practice contains no values that require units, it does describe methods to store and communicate data that do require units to be properly interpreted. The SI units required by this practice are to be regarded as standard. No other units of measurement are included in this practice. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 Personnel that are responsible for the creation, transfer, and storage of computed radiography NDE data will use this practice. This practice will define a set of information modules that along with the Practice E2339 and the DICOM standard will provide a standard means to organize CR inspection data. The CR inspection data may be displayed and analyzed on any device that conforms to the standard. Personnel wishing to view any CR inspection data stored in accordance with Practice E2339 may use this practice to help them decode and display the data contained in the DICONDE compliant inspection record.
