1.1 本规程通过以普遍接受的术语指定图像数据，促进了无损检测成像和数据采集设备的互操作性。该实践代表了无损检测成像系统或模式与NEMA标准出版物《医学数字成像和通信》（DICOM，见）的协调http://medical.nema.org)，图像数据采集、审查、存储和归档的国际标准。此外，本实践将提供一套标准的工业NDE特定信息对象定义，这些定义超出了标准DICOM模式的范围。本实践的目标是提供一个标准，根据该标准，符合ASTM DICONDE格式的任何系统都可以显示无损检测图像/信号数据，而不管使用哪种无损检测模式来获取数据。 1.2 制定本规程是为了克服在归档或分析各种无损检测技术（每种技术均使用专有数据采集系统）的数据时出现的问题。随着数据采集方式的发展，过去采集的数据必须保持可破译性。本实践提出了一种图像数据文件格式，其方式是，无论无损检测技术如何变化，都能保留所有技术参数和图像文件。这种做法还允许在单个工作站上查看各种图像类型（CT、CR、超声波、红外和涡流），同时保留所有相关技术参数和图像文件。 本规程涉及无损检测成像设备之间的数字信息交换。 1.3 本惯例未规定: 1.3.1 对实现成像设备的DICONDE标准所需的所有信息的完整描述。本文件必须与特定于方法的DICONDE标准实践文件之一和DICOM标准一起使用，以完整描述实现成像模态的DICONDE标准所需的所有要求。看见 2.1 方法特定标准实践文件的当前列表。 1.3.2 评估实施是否符合标准的测试或验证程序。 证明一致性的最佳实践可以在实践中找到 E3147 . 1.3.3 声明符合性的设备上标准任何功能的实现细节。 1.3.4 通过集成一组设备（每个设备都声称符合DICONDE或DICOM）实现的系统预期的全部特性和功能。 1.4 单位- 尽管本实践不包含需要单位的值，但它确实描述了需要正确解释单位的存储和通信数据的方法。本规程要求的国际单位应视为标准。本标准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）。本标准的用户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（TBT）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》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 负责在系统之间传输NDE数据的人员将使用本标准。本实践将定义一组NDE信息对象定义，该定义与DICOM标准一起将提供组织图像数据的标准方法。一旦生成一致性声明，NDE图像数据可显示在符合标准的任何成像/分析设备上。使用NDE特定对象定义和DICOM接受的定义开发一致性声明的过程，将提供一种在不丢失信息的情况下自动、透明地在符合要求的设备之间进行通信的方法。 注1: 需要了解现有的DICOM标准，才能生成一致性声明，从而促进数据传输。

1.1 This practice facilitates the interoperability of NDE imaging and data acquisition equipment by specifying the image data in commonly accepted terms. This practice represents a harmonization of NDE imaging systems, or modalities, with the NEMA Standards Publication titled Digital Imaging and Communications in Medicine (DICOM, see http://medical.nema.org), an international standard for image data acquisition, review, storage and archival. In addition, this practice will provide a standard set of industrial NDE specific information object definitions, which travel beyond the scope of standard DICOM modalities. The goal of this practice is to provide a standard by which NDE image/signal data may be displayed on by any system conforming to the ASTM DICONDE format, regardless of which NDE modality was used to acquire the data. 1.2 This practice has been developed to overcome the issues that arise when archiving or analyzing the data from a variety of NDE techniques, each using proprietary data acquisition systems. As data acquisition modalities evolve, data acquired in the past must remain decipherable. This practice proposes an image data file format in such a way that all the technique parameters, along with the image file, are preserved, regardless of changes in NDE technology. This practice will also permit the viewing of a variety of image types (CT, CR, Ultrasonic, Infrared, and Eddy Current) on a single workstation, maintaining all of the pertinent technique parameters along with the image file. This practice addresses the exchange of digital information between NDE imaging equipment. 1.3 This practice does not specify: 1.3.1 A complete description of all the information necessary to implement the DICONDE standard for an imaging modality. This document must be used in conjunction with one of the method-specific DICONDE Standard Practice documents and the DICOM Standard to completely describe all the requirements necessary to implement the DICONDE standard for an imaging modality. See 2.1 of this document for a current list of the method-specific standard practice documents. 1.3.2 A testing or validation procedure to assess an implementation's conformance to the standard. Best practices for demonstrating conformance can be found in Practice E3147 . 1.3.3 The implementation details of any features of the standard on a device claiming conformance. 1.3.4 The overall set of features and functions to be expected from a system implemented by integrating a group of devices each claiming DICONDE or DICOM conformance. 1.4 Units— 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 standard. 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 transfer of NDE data between systems will use this standard. This practice will define a set of NDE information object definitions that along with the DICOM standard will provide a standard means to organize image data. Once conformance statements have been generated, the NDE image data may be displayed on any imaging/analysis device that conforms to the standard. This process of developing conformance statements with both the NDE specific object definitions and the DICOM accepted definitions, will provide a means to automatically and transparently communicate between compliant equipment without loss of information. Note 1: Knowledge and understanding of the existing DICOM standard will be required to generate conformance statements and thereby facilitate the data transfer.
