Terminology3.1 Definitions:3.1.1 Nondestructive evaluation terms used in this practicecan be found in Terminology E1316.3.1.2 DICONDE terms used in this practice can be found inTerminology E2339 and E3147.4. Summary of Guide4.1 DICOM provides rich methods for managing thedisplay,

21、transfer and storage of a wide variety of digital testdata. An explicit list of the digital data covered can be found inthe DICOM standard. These modalities are referred to asStandard SOP Classes.4.2 DICOM provides the flexibility to address the storage ofdigital data not expressly defined in a Stan

22、dard SOP Class.4.2.1 Standard Extended SOP Classes extend Standard SOPClasses with additional data that is user optional. Use of aStandard Extended SOP Class does not impact the interoper-ability of the SOP Class.4.2.2 Specialized SOP Classes are derived from StandardSOP Class but include changes to

23、 the mandatory data associ-ated with the SOP Class. Use of a Specialized SOP Class doesimpact interoperability and requires updates to the DICOM andDICONDE standards to ensure interoperability.4.3 The DICONDE standard is comprised of both StandardExtended and Specialized SOP Classes.4.3.1 Standard E

24、xtended SOP Classes are utilized whenthere is a medical imaging modality that closely aligns with anondestructive test method. Examples of this are E2663DICONDE for Ultrasonic Test Methods and E2699 DICONDEfor Digital Radiographic Test Methods. The DICONDE stan-dard practices that utilize Standard E

25、xtended SOP Classesmaintain the most interoperability with DICOM compliantdevices.4.3.2 Specialized SOP Classes are utilized for test methodsthat do not have an equivalent medical imaging modality. Anexample of this is E2934 DICONDE for Eddy Current TestMethods. In this case, the DICOM standard offi

26、cially recog-nizes the existence of the DICONDE Specialized SOP Classesand will not create a future version of the DICOM standard thatconflicts with the DICONDE Specialized SOP Classes. TheDICONDE standard practices that are based on SpecializedSOP Classes result in a low level of interoperability w

27、ithDICOM compliant devices. In most cases, DICOM compliantdevices will not accept the data since it is not a DICOMStandard SOP Class.4.3.3 The purpose of DICONDE is to provide a standardway to universally access the NDT data and associatedmetadata produced by NDT systems. DICONDE facilitates theinte

28、roperability of NDE imaging and data acquisition equip-ment by specifying the image data in commonly acceptedterms. It describes a standard protocol to display, transfer, andstore the NDT data, utilizing the protocol established byDICOM, providing a means to automatically and transparentlycommunicat

29、e between compliant equipment without loss ofinformation. As such, it also provides a standard methodologyto organize and retain the NDT data. The overall organizationof ASTMs DICONDE standards and their relationship toDICOM is shown in Fig. 1.4.4 NDT systems using DICONDE should do so in amanner th

30、at guarantees their ability to interoperate with otherNDT systems that implement DICONDE. The inability touniversally access the data and associated metadata producedby NDT systems defeats the purpose of DICONDE.4.4.1 Vendors utilizing DICONDE are required to provide aconformance statement for each

31、product claiming DICONDEconformance. The conformance statement is a technical docu-ment that outlines the relevant services for comparison withother systems to ensure communications work effectively.4.4.2 In practice, it is impossible for vendors to ensureDICONDE systems interoperate in isolation. S

32、pecific testprotocols are needed for vendors to be able to verify the abilityof products claiming DICONDE conformance with similarproducts from other vendors.4.4.3 For widespread adoption, systems claiming DI-CONDE conformance should be able to be verified for the enduser.

Procedure6.1 By utilizing Standard Extended SOP Classes, DI-CONDE maintains a maximum interoperability with DICOM.Only the minimum amount of met

36、adata necessary is changed tocreate the DICONDE SOP classes.As a result, the test-method-specific DICONDE standard practice documents do not com-pletely define all the required metadata.6.1.1 To maximize DICONDE interoperability withDICOM, only the differences in the metadata between theDICONDE and

37、DICOM SOP classes are documented in theDICONDE standard practice documents. As shown in Fig. 2,itis necessary for the user of a DICONDE standard practice torefer to both Part 3 and Part 6 of the DICOM standard toidentify all the metadata required for interoperability.6.1.2 Some of the metadata added

38、 for DICONDE is appli-cable to multiple test methods. The metadata that is nottest-method-specific is located in the E2339 DICONDE stan-dard practice. Users of the DICONDE test-method-specificstandard practices will need to refer to E2339 to identify all themetadata required for interoperability as

39、suggested by Fig. 2.6.2 The digital data from test methods not explicitly coveredby a test-method-specific DICONDE standard practice maystill be able to be stored using DICONDE. If the digital datafrom the test method has an analog in Part 4 of the DICOMstandard then a Standard Extended SOP Class ba

40、sed on theDICOM Standard SOP class may be used. The standard SOPclass can be extended using previously defined metadata fromE2339 and Part 6 of the DICOM standard. The metadata alsoFIG. 1 Overview of the Organization of the Family of ASTM DICONDE StandardsFIG. 2 Document Relationships for DICONDE Te

41、st Method Standard PracticesE3169 183can be extended using private attributes as described in Part 7of the DICOM standard. This relationship is shown in Fig. 3.An example of a test method that could be handled using thisprocess is the borescope test method. Borescope testing datacould be stored in D

42、ICONDE format using either the VisibleLight Endoscopic Image or Video Endoscopic Image StandardSOP classes and E2339 to create Standard Extended SOPClasses. If the use of a Standard Extended SOP Class becomeswidespread, it should be considered for the creation of atest-method-specific DICONDE standa

43、rd practice.6.3 A test method with digital data that does not have ananalog in medical imaging should utilize a Specialized SOPClass by creating a test-method-specific DICONDE standardpractice.6.4 A DICONDE conformance statement is a technicaldocument that outlines the relevant services supported by

44、 theproduct including specific SOP Classes. The DICONDE stan-dard permits not supporting all DICONDE SOP Classes. Theconformance statement is the primary method of determining ifa product is appropriate for a given application. Interpretingconformance statements starts with information found inE3147

45、 on the interoperability of DICONDE systems. Addi-tional supporting information can be found in Part 2 of theDICOM standard as well as the general and test-method-specific DICONDE standards. The relationship is shown inFig. 4.6.5 DICONDE products should be able to display and storeNDT data such that

46、 this data can be universally accessed asdescribed in the products conformance statement. Validatingthe DICONDE product may be done in isolation. Recom-mended validation testing protocols for DICONDE manufac-turers against a reference validator are provided in E3147 onthe interoperability of DICONDE

47、 products. The examplereference validator can be modified to include new StandardExtended SOP Classes and Specialized SOP Classes.6.6 DICONDE products should be able to communicatewith DICONDE products from diverse manufacturers as de-scribed in the products conformance statement. Testing theinterop

48、erability of a DICONDE product cannot be done inisolation. While interoperability testing can be done against areference implementation of the DICONDE standard, to ensureinteroperability, testing should be done with DICONDE prod-ucts from multiple manufacturers. Recommended interoper-ability testing

49、 protocols for DICONDE manufacturers againstboth a reference implementation and DICONDE products fromother manufacturers are provided in E3147 on the interoper-ability of DICONDE products.6.7 Purchasers of DICONDE products that are required tocommunicate with other DICONDE products need a method toverify the interoperability of those products. It is impossible forthe manufacturers of DICONDE products to test the interop-erability of their product against all other products claimingDICONDE conformance. The purchaser needs to verify theinteroperability of products before purchase.
