Thisdocument is intended to be used in conjunction with PracticeE2339 on Digital Imaging and Communication in Nondestruc-tive Evaluat
4、ion (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 goal of Practice E
5、2339, 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 to all NDE modaliti
6、es. 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 ultrasonic testequ
7、ipment 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 and test resultsar
8、e 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 thestandard on a device c
9、laiming 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 communicate datathat
10、 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. It is theresponsibi
11、lity of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

17、ted States14. 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 dictionary and common communicationprotocols. To further standardization, the el
18、ements 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 information modules specifiedin Practice E2339 do not cover the informatio
19、n 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 andinformation modules necessary for ultrasonic insp
20、ection.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 froma specific modality. This practice contains the informa
21、tionobject 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 information modules that along withPractice E2339 and the DICOM standard
22、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 inspection data stored in DICONDEformat may use this document to help them decode
23、and displaythe data contained in the DICONDE compliant inspectionrecord.6.
