Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This practice facilitates the interoperability of digitalX-ray imaging eq
3、uipment by specifying image data transferand archival methods in commonly accepted terms. Thisdocument is intended to be used in conjunction with PracticeE2339 on Digital Imaging and Communication in Nondestruc-tive Evaluation (DICONDE). Practice E2339 defines an indus-trial adaptation of the NEMA S
4、tandards Publication titledDigital Imaging and Communications in Medicine (DICOM,see http:/medical.nema.org), an international standard forimage data acquisition, review, storage and archival storage.The goal of Practice E2339, commonly referred to as DI-CONDE, is to provide a standard that facilita
5、tes the display andanalysis of NDE results on any system conforming to theDICONDE standard. Toward that end, Practice E2339 providesa data dictionary and a set of information modules that areapplicable to all NDE modalities. This practice supplementsPractice E2339 by providing information object def
6、initions,information modules and a data dictionary that are specific todigital X-ray test methods.1.2 This practice has been developed to overcome the issuesthat arise when analyzing or archiving data from digital X-raytest equipment using proprietary data transfer and storagemethods. As digital tec
7、hnologies evolve, data must remaindecipherable through the use of open, industry-wide methodsfor data transfer and archival storage. 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
8、 digital technology.1.3 This practice does not specify:1.3.1 A testing or validation procedure to assess an imple-mentations conformance 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
9、 be ex-pected from a system implemented by integrating a group ofdevices each claiming DICONDE conformance.1.4 Although this practice 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
10、this practice are to be regarded as standard. Noother units of measurement are included in this standard.1.5 This standard does not 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 and
11、 health practices and determine the applica-bility of regulatory limitations prior to use.2.

17、ed in this practice aredefined in Practice E2597.4. Summary of Practice4.1 A fundamental principle of 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-muni
18、cation protocols. To further standardization, the elementsin the data dictionary are organized into 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 sp
19、ecifiedin Practice E2339 do not cover the information storagerequirements for each individual modality (CT, DR, 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
20、andinformation modules necessary for digital X-ray inspection.4.3 The 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 from
21、a specific modality. This practice contains information objectdefinitions for digital X-ray inspection.5. 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 modu
22、les that alongwith Practice E2339 and the 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. Person-nel wishing to view any digital X-ray inspection dat
23、a storedaccording to Practice E2339 may use this document to helpthem decode and display the data contained in the DICONDE-compliant inspection record.6.
