3、uipment using Digital Detector Arrays(DDA) as described in E2698 by specifying image data transferand archival methods in commonly accepted terms. A separatepractice, E2738, addresses this topic for digital X-ray imagingequipment using Computed Radiography (CR). This documentis intended to be used i
4、n conjunction with Practice E2339 onDigital Imaging and Communication in Nondestructive Evalu-ation (DICONDE). Practice E2339 defines an industrial adap-tation of the NEMA Standards Publication titled DigitalImaging and Communications in Medicine (DICOM, seehttp:/medical.nema.org), an international
5、standard for imagedata acquisition, review, storage and archival storage. The goalof Practice E2339, commonly referred to as DICONDE, is toprovide a standard that facilitates the display and analysis ofNDE results on any system conforming to the DICONDEstandard. Toward that end, Practice E2339 provi
6、des a datadictionary and a set of information modules that are applicableto all NDE modalities. This practice supplements PracticeE2339 by providing information object definitions, informationmodules and a data dictionary that are specific to digital X-raytest methods.1.2 This practice has been deve
7、loped to overcome the issuesthat arise when analyzing or archiving data from digital X-raytest equipment using proprietary data transfer and storagemethods. As digital technologies evolve, data must remaindecipherable through the use of open, industry-wide methodsfor data transfer and archival stora
8、ge. This practice defines amethod where all the digital X-ray technique parameters andtest results are communicated and stored in a standard mannerregardless of changes in digital technology.1.3 This practice does not specify:1.3.1 A testing or validation procedure to assess an imple-mentations conf
9、ormance to the standard.1.3.2 The implementation details of any features of thestandard on a device claiming conformance.1.3.3 The overall set of features and functions to be ex-pected from a system implemented by integrating a group ofdevices each claiming DICONDE conformance.1.4 Although this prac
10、tice contains no values that requireunits, it does describe methods to store and communicate datathat do require units to be properly interpreted. The SI unitsrequired by this practice are to be regarded as standard. Noother units of measurement are included in this standard.1.5 This standard does n
11、ot purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety, health, and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.6 This international
12、standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards, Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade (TBT) Committee.

19、 in this practicecan be found in Standard Terminology for NondestructiveExaminations, E1316.3.1.2 DICONDE terms used in this practice are defined inPractice E2339.3.1.3 Digital detector array terms used in this practice aredefined in Practice E2597.4. Summary of Practice4.1 A fundamental principle o
20、f DICONDE is the use ofstandard definitions and attribute formats for data communica-tion and storage. This means all systems that are DICONDEcompliant use a common data dictionary and common com-munication protocols. To further standardization, the elementsin the data dictionary are organized into
21、common groupsreferred to as information modules. The data dictionary andinformation modules common to all NDE modalities aredefined in Practice E2339.4.2 The data dictionary and information modules specifiedin Practice E2339 do not cover the information storagerequirements for each individual modali
22、ty (CT, DDA, CR, UT,etc.). Additions to the data dictionary and information modulesare required to support the individual modalities. This practicecontains the additions to the DICONDE data dictionary andinformation modules necessary for digital X-ray inspectionusing Digital Detector Arrays.4.3 The
23、highest organizational level in the DICONDEinformation model is the information object definition (IOD).An information object definition is a collection of the infor-mation modules necessary to represent a set of test results froma specific modality. This practice contains information objectdefiniti

Significance and Use5.1 Personnel that are responsible for the creation, transfer,and storage of digital X-ray test results will use this standard.This practice defines a set of information modules that alongwith Practice E2339 and the
25、 DICOM standard provide astandard means to organize digital X-ray test parameters andresults. The digital X-ray test results may be displayed andanalyzed on any device that conforms to this standard.
