1、Designation: E2738 10Standard 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. Scope1.1 This practice facilitates the interoperability of computedradiography (CR) im
3、aging 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 in
4、dustrial 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
5、 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 by
6、 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 manner
8、 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 f
9、eatures 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.2.

Summary of Practice4.1 A fundamental principle of DICONDE is the use ofstandard definitions and attribute formats for data communica-tion and storage. This m
13、eans all systems that are DICONDEcompliant use a common data dictionary and common com-munication 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
