1、Designation: E2934 14 (Reapproved 2018)Standard Practice forDigital Imaging and Communication in NondestructiveEvaluation (DICONDE) for Eddy Current (EC) Test Methods1This standard is issued under the fixed designation E2934; the number immediately following the designation indicates the year oforig
2、inal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice facilitates the interoperability of eddycurrent i
3、maging and data acquisition equipment by specifyingthe image data transfer and archival storage in commonlyaccepted terms. This document is intended to be used inconjunction with Practice E2339 on Digital Imaging andCommunication in Nondestructive Evaluation (DICONDE).Practice E2339 defines an indus
4、trial adaptation of the NEMAStandards Publication titled Digital Imaging and Communica-tions in Medicine (DICOM, see http:/medical.nema.org), aninternational standard for image data acquisition, review,storage and archival storage. The goal of Practice E2339,commonly referred to as DICONDE, is to pr
5、ovide a standardthat facilitates the display and analysis of NDE results on anysystem conforming to the DICONDE standard. Toward thatend, Practice E2339 provides a data dictionary and a set ofinformation modules that are applicable to all NDE modalities.This practice supplements Practice E2339 by pr
6、oviding infor-mation object definitions, information modules and a datadictionary that are specific to eddy current test methods.1.2 This practice has been developed to overcome the issuesthat arise when analyzing or archiving data from eddy currenttest equipment using proprietary data transfer and
7、storagemethods. As digital technologies evolve, data must remaindecipherable through the use of open, industry-wide methodsfor data transfer and archival storage. This practice defines amethod where all the eddy current technique parameters andinspection data are communicated and stored in a standar
8、dmanner regardless 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 conformance to the standard,1.3.2 The implementation details of any features of thestandard on a device claiming conformance, or1.3.3 The overa
9、ll 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 practice contains no values that requireunits, it does describe methods to store and communicate datathat do require units to be properly in
10、terpreted. The valuesstated in SI units are to be regarded as standard. No other unitsof 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 establi
11、sh appro-priate safety, health, and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles fo

18、TBT) Committee.14. 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-munication protocols. To further stan
19、dardization, 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 specifiedin Practice E2339 do not c
20、over the information storagerequirements for each individual modality (ComputedTomography, Digital Radiography, Computed Radiography,Ultrasonic, etc.). Additions to the data dictionary and informa-tion modules are required to support the individual modalities.This practice contains the additions to
21、the DICONDE datadictionary and information modules necessary for eddy currentinspection.4.3 The highest organizational level in the DICONDEinformation model is the information object definition (IOD).The information object definition is a collection of informationmodules necessary to represent a set
22、 of examination resultsfrom a specific modality. This practice contains informationobject definitions necessary for eddy current inspection.5. Significance and Use5.1 Personnel that are responsible for the creation, transfer,and storage of eddy current NDE test results will use thisstandard. This pr
23、actice defines a set of information modulesthat along with the Practice E2339 and the DICOM standardprovides a standard means to organize eddy current testparameters and results. The eddy current examination resultsmay be displayed or analyzed on any device that conforms tothe standard. Personnel wi
