1、Designation: E2738 11Standard Practice forDigital Imaging and Communication NondestructiveEvaluation (DICONDE) for Computed Radiography (CR) TestMethods1This standard is issued under the fixed designation E2738; the number immediately following the designation indicates the year oforiginal adoption
2、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. Scope*1.1 This practice facilitates the interoperability of computedradiography (CR) i
3、maging and data acquisition equipment byspecifying image data transfer and archival storage methods incommonly accepted terms. This practice is intended to be usedin conjunction with Practice E2339 on Digital Imaging andCommunication in Nondestructive Evaluation (DICONDE).Practice E2339 defines an i
4、ndustrial 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 t
5、o provide 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 b
6、y providing infor-mation object definitions, information modules and a datadictionary that are specific to computed radiography testmethods.1.2 This practice has been developed to overcome the issuesthat arise when analyzing or archiving data from CR testequipment using proprietary data transfer and
7、 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 standard CR technique parameters and test results arecommunicated and stored in a standard manne
8、r 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 claiming conformance.1.3.3 The overall set of
9、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 interpreted.
10、 The SI unitsrequired by this practice are to be regarded as standard. Noother units of measurement are included in this practice.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 establis
11、h appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

To fur
17、ther 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 specifiedin Practice E2339
18、 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 andinformation modules n
19、ecessary for CR 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 froma specific modality. This practice
20、contains information objectdefinitions for CR inspection.5. Significance and Use5.1 Personnel that are responsible for the creation, transfer,and storage of computed radiography NDE data will use thispractice. This practice will define a set of information modulesthat along with the Practice E2339 a
21、nd the DICOM standardwill provide a standard means to organize CR inspection data.The CR inspection data may be displayed and analyzed on anydevice that conforms to the standard. Personnel wishing toview any CR inspection data stored in accordance with PracticeE2339 may use this practice to help the
22、m decode and displaythe data contained in the DICONDE compliant inspectionrecord.6. Information Object Definitions6.1 NDE Computed Radiography Image IOD Description:6.1.1 The NDE Computed Radiography (CR) Image Infor-mation Object Definition specifies an image that has beencreated by a computed radi
