3、 Defense.1. Scope*1.1 This practice facilitates the interoperability of digital X-ray imaging equipment by specifying image data transfer andarchival methods in commonly accepted terms. This document is intended to be used in conjunction with Practice E2339 on DigitalImaging and Communication in Non
4、destructive Evaluation (DICONDE). Practice E2339 defines an industrial adaptation of theNEMA Standards Publication titled Digital Imaging and Communications in Medicine (DICOM, see http:/medical.nema.org), aninternational standard for image data acquisition, review, storage and archival storage. The
5、 goal of Practice E2339, commonlyreferred to as DICONDE, is to provide a standard that facilitates the display and analysis of NDE results on any system conformingto the DICONDE standard. Toward that end, Practice E2339 provides a data dictionary and a set of information modules that areapplicable t
6、o all NDE modalities. This practice supplements Practice E2339 by providing information object definitions,information modules and a data dictionary that are specific to digital X-ray test methods.1.2 This practice has been developed to overcome the issues that arise when analyzing or archiving data
7、 from digital X-ray testequipment using proprietary data transfer and storage methods. As digital technologies evolve, data must remain decipherablethrough the use of open, industry-wide methods for data transfer and archival storage. This practice defines a method where allthe digital X-ray techniq
8、ue parameters and test results are communicated and stored in a standard manner regardless of changesin digital technology.1.3 This practice does not specify:1.3.1 A testing or validation procedure to assess an implementations conformance to the standard.1.3.2 The implementation details of any featu
9、res of the standard on a device claiming conformance.1.3.3 The overall set of features and functions to be expected from a system implemented by integrating a group of devices eachclaiming DICONDE conformance.1.4 Although this practice contains no values that require units, it does describe methods
10、to store and communicate data thatdo require units to be properly interpreted. The SI units required by this practice 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 the safety concerns, if any, associate
11、d with its use. It is the responsibilityof the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatorylimitations prior to use.2.

18、tandard Terminology for NondestructiveExaminations, E1316.3.1.2 DICONDE terms used in this practice are defined in Practice E2339.3.1.3 Digital detector array terms used in this practice are defined in Practice E2597.4. Summary of Practice4.1 A fundamental principle of DICONDE is the use of standard
19、 definitions and attribute formats for data communication andstorage. This means all systems that are DICONDE compliant use a common data dictionary and common communicationprotocols. To further standardization, the elements in the data dictionary are organized into common groups referred to asinfor
20、mation modules. The data dictionary and information modules common to all NDE modalities are defined in Practice E2339.4.2 The data dictionary and information modules specified in Practice E2339 do not cover the information storage requirementsfor each individual modality (CT, DR, CR, UT, etc.). Add
21、itions to the data dictionary and information modules are required tosupport the individual modalities. This practice contains the additions to the DICONDE data dictionary and information modulesnecessary for digital X-ray inspection.4.3 The highest organizational level in the DICONDE information mo
22、del is the information object definition (IOD). Aninformation object definition is a collection of the information modules necessary to represent a set of test results from a specificmodality. This practice contains information object definitions for digital X-ray inspection.5. Significance and Use5
23、.1 Personnel that are responsible for the creation, transfer, and storage of digital X-ray test results will use this standard. Thispractice defines a set of information modules that along with Practice E2339 and the DICOM standard provide a standard meansto organize digital X-ray test parameters an
24、d results. The digital X-ray test results may be displayed and analyzed on any devicethat conforms to this standard. Personnel wishing to view any digital X-ray inspection data stored according to Practice E2339 mayuse this document to help them decode and display the data contained in the DICONDE-c
