3、nse.1. Scope*1.1 This practice facilitates the interoperability of ultrasonicimaging equipment by specifying image data transfer andarchival storage methods in commonly accepted terms. Thisdocument is intended to be used in conjunction with PracticeE2339 on Digital Imaging and Communication in Nonde
4、struc-tive Evaluation (DICONDE). Practice E2339 defines an indus-trial adaptation of the NEMA Standards Publication titledDigital Imaging and Communications in Medicine (DICOM,see http:/medical.nema.org), an international standard forimage data acquisition, review, transfer and archival storage.The
5、goal of Practice E2339, commonly referred to asDICONDE, is to provide a standard that facilitates the displayand analysis of NDE test results on any system conforming tothe DICONDE standard. Toward that end, Practice E2339provides a data dictionary and set of information modules thatare applicable t
6、o all NDE modalities. This practice supple-ments Practice E2339 by providing information objectdefinitions, information modules and data dictionary that arespecific to ultrasonic test methods.1.2 This practice has been developed to overcome the issuesthat arise when analyzing or archiving data from
7、ultrasonic testequipment using proprietary data transfer and storage methods.As digital technologies evolve, data must remain decipherablethrough the use of open, industry-wide methods for datatransfer and archival storage. This practice defines a methodwhere all the ultrasonic technique parameters
8、and test resultsare communicated and stored in a standard format regardless ofchanges 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 thestan
9、dard 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 practice contains no values that requireunits, it does describe methods to store and co
10、mmunicate 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 not purport to address all of thesafety concerns, if any, associated with its use. I
11、t 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 standard was developed in accor-dance with internationally recognized principles on

Terminology3.1 Definitions:3.1.1 Nondestructive evaluation terms used in this practicecan be found in Termi
19、nology E1316.3.1.2 DICONDE terms used in this practice are defined inPractice E2339.4. Summary of Practice4.1 A fundamental principle of DICONDE is the use ofstandard definitions and formats for data communication andstorage. This means all systems that are DICONDE compliantuse a common data diction
20、ary and common communicationprotocols. To further standardization, the elements in the datadictionary are organized into common groups referred to asinformation modules. The data dictionary and informationmodules common to all NDE modalities are defined in PracticeE2339.4.2 The data dictionary and i
21、nformation modules specifiedin 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 DIC
22、ONDE data dictionary andinformation modules necessary for ultrasonic 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
23、 test results froma specific modality. This practice contains the informationobject definitions for ultrasonic inspection.5. Significance and Use5.1 Personnel that are responsible for the creation, transfer,and storage of ultrasonic test results will use this standard. Thispractice defines a set of
24、information modules that along withPractice E2339 and the DICOM standard provide a standardmeans to organize ultrasonic test parameters and results. Theultrasonic test results may be displayed and analyzed on anydevice that conforms to this standard. Personnel wishing toview any ultrasonic inspectio
25、n data stored in DICONDEformat may use this document to help them decode and displaythe data contained in the DICONDE compliant inspectionrecord.6.
