Standard Practice for Digital Imaging and Communication in Nondestructive Evaluation (DICONDE)

SIGNIFICANCE AND USE
5.1 Personnel that are responsible for the transfer of NDE data between systems will use this standard. This practice will define a set of NDE information object definitions that along with the DICOM standard will provide a standard means to organize image data. Once conformance statements have been generated, the NDE image data may be displayed on any imaging/analysis device that conforms to the standard. This process of developing conformance statements with both the NDE specific object definitions and the DICOM accepted definitions, will provide a means to automatically and transparently communicate between compliant equipment without loss of information.
Note 1: Knowledge and understanding of the existing DICOM standard will be required to generate conformance statements and thereby facilitate the data transfer.
SCOPE
1.1 This practice facilitates the interoperability of NDE imaging and data acquisition equipment by specifying the image data in commonly accepted terms. This practice represents a harmonization of NDE imaging systems, or modalities, with the NEMA Standards Publication titled Digital Imaging and Communications in Medicine (DICOM, see http://medical.nema.org), an international standard for image data acquisition, review, storage and archival. In addition, this practice will provide a standard set of industrial NDE specific information object definitions, which travel beyond the scope of standard DICOM modalities. The goal of this practice is to provide a standard by which NDE image/signal data may be displayed on by any system conforming to the ASTM DICONDE format, regardless of which NDE modality was used to acquire the data.  
1.2 This practice has been developed to overcome the issues that arise when archiving or analyzing the data from a variety of NDE techniques, each using proprietary data acquisition systems. As data acquisition modalities evolve, data acquired in the past must remain decipherable. This practice proposes an image data file format in such a way that all the technique parameters, along with the image file, are preserved, regardless of changes in NDE technology. This practice will also permit the viewing of a variety of image types (CT, CR, Ultrasonic, Infrared, and Eddy Current) on a single workstation, maintaining all of the pertinent technique parameters along with the image file. This practice addresses the exchange of digital information between NDE imaging equipment.  
1.3 This practice does not specify:  
1.3.1 A complete description of all the information necessary to implement the DICONDE standard for an imaging modality. This document must be used in conjunction with one of the method-specific DICONDE Standard Practice documents and the DICOM Standard to completely describe all the requirements necessary to implement the DICONDE standard for an imaging modality. See 2.1 of this document for a current list of the method-specific standard practice documents.  
1.3.2 A testing or validation procedure to assess an implementation's conformance to the standard. Best practices for demonstrating conformance can be found in Practice E3147.  
1.3.3 The implementation details of any features of the standard on a device claiming conformance.  
1.3.4 The overall set of features and functions to be expected from a system implemented by integrating a group of devices each claiming DICONDE or DICOM conformance.  
1.4 Units—Although this practice contains no values that require units, it does describe methods to store and communicate data that do require units to be properly interpreted. The SI units required by this practice are to be regarded as standard. No other units of measurement are included in this standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and de...

Overview

ASTM E2339-21: Standard Practice for Digital Imaging and Communication in Nondestructive Evaluation (DICONDE) sets out a framework for achieving interoperability between nondestructive evaluation (NDE) imaging systems. Developed by ASTM International, this standard harmonizes industrial NDE imaging data management with the widely adopted DICOM (Digital Imaging and Communications in Medicine) standard, enabling consistent acquisition, storage, review, and archival of NDE image data. By defining NDE-specific information object definitions, ASTM E2339-21 ensures that imaging and data from varied acquisition modalities can be transferred and displayed across compliant devices, regardless of the original system or technology used for data capture.

Key Topics

  • Interoperability for NDE Imaging: ASTM E2339-21 provides a standardized approach to organize and transfer image and signal data from NDE systems, overcoming the challenges of proprietary data formats and facilitating long-term accessibility and compatibility.
  • Harmonization with DICOM: The practice bridges industrial NDE imaging with medical imaging standards, reusing DICOM’s robust model while adapting terminology and modules for industrial applications (for example, replacing 'Patient' with 'Component').
  • Conformance Statements: Implementers generate conformance statements describing the supported information objects and protocols. This transparent specification allows different systems to communicate without loss of critical data.
  • Adaptable to Multiple Modalities: The standard supports varied image types (Computed Tomography [CT], Computed Radiography [CR], Ultrasonic, Infrared, Eddy Current, and more) and ensures that essential technique parameters are retained and accessible.
  • Preservation of Legacy Data: E2339-21 addresses backward compatibility, allowing images and associated parameters from legacy NDE technologies to remain interpretable as systems evolve.
  • Industrial-Specific Extensions: Where industrial needs differ from medical standards, the practice defines new modules and attributes (such as 'Component Manufacturer' or 'Material Thickness') to capture unique NDE requirements.

Applications

ASTM E2339-21 is crucial for organizations involved in digital NDE imaging, including:

  • Aerospace, Energy, and Manufacturing: Enables standardized digital imaging workflows for component inspection, defect analysis, and regulatory compliance documentation.
  • NDE Data Management: Facilitates easy exchange, archiving, and retrieval of inspection data across differing hardware and software platforms, reducing vendor lock-in.
  • Equipment Integration: Supports integration of multiple NDE modalities into unified review and analysis environments, improving efficiency in inspection processes.
  • Quality Assurance and Long-Term Archival: Ensures that NDE imaging data, along with inspection parameters and environmental conditions, are retained in non-proprietary, accessible formats for audit, certification, and historical reference.
  • Regulated Environments: Assures conformance to industry and government mandates for digital data traceability and interoperability, as required by sectors such as defense and infrastructure.

Related Standards

ASTM E2339-21 is intended to be used together with additional method-specific and foundational standards, including:

  • ASTM E1316: Terminology for Nondestructive Examinations
  • ASTM E2663: DICONDE for Ultrasonic Test Methods
  • ASTM E2699: DICONDE for Digital Radiographic Test Methods
  • ASTM E2738: DICONDE for Computed Radiography Test Methods
  • ASTM E2767: DICONDE for X-ray Computed Tomography Test Methods
  • ASTM E2934: DICONDE for Eddy Current Test Methods
  • ASTM E3147: Practice for Evaluating DICONDE Interoperability
  • ASTM E3169: Guide for DICONDE Implementation
  • NEMA DICOM (PS3/ISO 12052): Digital Imaging and Communications in Medicine

Summary

ASTM E2339-21 plays a pivotal role in digitalizing nondestructive evaluation workflows, promoting data interoperability, and ensuring the integrity and longevity of industrial inspection records. By aligning industrial imaging with proven medical imaging standards and adding NDE-specific elements, it enables seamless communication, enhances efficiency, and supports compliance in critical sectors.

Standard Practice for
Digital Imaging and Communication in Nondestructive
Evaluation (DICONDE)
This standard is issued under the fixed designation E2339; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the U.S. Department of Defense.
1. Scope*
1.1 This practice facilitates the interoperability of NDE imaging and data acquisition equipment by specifying the image data in
commonly accepted terms. This practice represents a harmonization of NDE imaging systems, or modalities, with the NEMA
Standards Publication titled Digital Imaging and Communications in Medicine (DICOM, see http://medical.nema.org), an
international standard for image data acquisition, review, storage and archival. In addition, this practice will provide a standard set
of industrial NDE specific information object definitions, which travel beyond the scope of standard DICOM modalities. The goal
of this practice is to provide a standard by which NDE image/signal data may be displayed on by any system conforming to the
ASTM DICONDE format, regardless of which NDE modality was used to acquire the data.
1.2 This practice has been developed to overcome the issues that arise when archiving or analyzing the data from a variety of NDE
techniques, each using proprietary data acquisition systems. As data acquisition modalities evolve, data acquired in the past must
remain decipherable. This practice proposes an image data file format in such a way that all the technique parameters, along with
the image file, are preserved, regardless of changes in NDE technology. This practice will also permit the viewing of a variety of
image types (CT, CR, Ultrasonic, Infrared, and Eddy Current) on a single workstation, maintaining all of the pertinent technique
parameters along with the image file. This practice addresses the exchange of digital information between NDE imaging
equipment.
1.3 This practice does not specify:
1.3.1 A complete description of all the information necessary to implement the DICONDE standard for an imaging modality. This
document must be used in conjunction with one of the method-specific DICONDE Standard Practice documents and the DICOM
Standard to completely describe all the requirements necessary to implement the DICONDE standard for an imaging modality. See
Section 2.1 of this document for a current list of the method-specific standard practice documents.
1.3.2 A testing or validation procedure to assess an implementation’s conformance to the standard. Best practices for
demonstrating conformance can be found in Practice E3147.
1.3.3 The implementation details of any features of the standard on a device claiming conformance.
1.3.4 The overall set of features and functions to be expected from a system implemented by integrating a group of devices each
claiming DICONDE or DICOM conformance.
This practice is under the jurisdiction of ASTM Committee E07 on Nondestructive Testing and is the direct responsibility of Subcommittee E07.11 on Digital Imaging
and Communication in Nondestructive Evaluation (DICONDE).

1.4 Units—Although this practice contains no values that require units, it does describe methods to store and communicate data
that do require units to be properly interpreted. The SI units required by this practice are to be regarded as standard. No other units
of measurement are included in this standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety safety, health, and healthenvironmental practices and determine the
applicability of regulatory limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4. Summary of Practice
4.1 Guide E3169 provides an overview of the ASTM International standard practices that address DICONDE and assistance in
identifying the correct standard practices needed to implement specific use cases. That document should be the first document
utilized for any DICONDE application.
E2339 − 21
4.2 The basic concept of DICOM and DICONDE is the use of standardized data identifiers. This means all participants are using
the standardized data identifiers to represent the same information and have a common understanding of communication protocols
for mutual use.
4.2.1 DICOM was developed in liaison with ACR (the American College of Radiology) and NEMA (the National Electrical
Manufacturers Association) and other Standard Organizationsstandard organizations, including CEN TC251 in Europe and JIRA
in Japan, with review also by other organizations, including IEEE, HL7, and ANSI in the USA. The DICOM Standard is structured
as a multi-part document.
4.3 This practice will contain terms and definitions that apply to all NDT methods. DICONDE terms and definitions that apply
to a specific NDT method will be contained in a separate standard practice for that method as illustrated in Fig. 1. This practice
must be used in conjunction with the method-specific standard practices. For a list of method-specific standard practices, refer to
subsection 2.1 of this document. If no method-specific practice exists, the user should default back to the DICOM terms and
definitions for the modality associated with that test method.
4.4 The DICONDE practices will consist of descriptions of the attribute and object definitions that are specific to NDE (that is,
no equivalent counterpart in medicine) and provide standard database tag identifiers for use with the DICOM database already in
existence. The use of this practice is based upon and to be used in conjunction with the medical DICOM standard. This practice,
in conjunction with the DICOM standard, will set forth the requirements for the transfer and display of NDE image data from any
NDE image modalities equipment.
4.4.1 DICONDE, utilizing the existing DICOM database of object definitions, provides both replacement and additional module
definitions that represent a conversion between the medical community language present in DICOM, to the terminology
appropriate for NDE. For the DICONDE practices, only the attributes and object definitions that differ from the medical
implementation will be discussed. In the case where no replacement attribute or object exists, the DICOM standard should be
followed.
4.4.2 One of the inherited features of DICONDE is an internal structured grouping of images separate from the name or location
of the file, or both. The mandatory tags of Study Instance UID (0020,000D), Series Instance UID (0020,000E), and SOP Instance
UID (0008,0018) stored within each DICONDE object, uniquely identify each image and allow for the grouping of images into
series and study groups. This is a major advantage for datasets with large numbers of individual files, bringing them together into
a logical group for simplified access and management. A common example is with CT methods where many hundreds of individual
images are captured and logically grouped together for volumetric reconstruction.
4.5 As a superset of DICOM, DICONDE provides a standard for the file-level storage, network communication, and management
of evaluation data. While these three elements are contained within DICONDE, compliance does not require the support of all
three. For example, a system can produce DICONDE compliant files without needing to support network communications. The
capabilities are outlined in the conformance statement.
4.6 The key to interoperability using the DICOM standard is the conformance statement. This formal statement is associated with
a specific implementation of the DICOM standard. It specifies the service classes, information objects, communication protocols,
FIG. 1 DICONDE Document Relationships
E2339 − 21
and media storage application profiles supported by the implementation. Complete information on DICOM conformance
statements, including several examples, can be found in Part 2 of the DICOM standard.
4.6.1 Specific implementations of the DICONDE standard should also provide conformance statements. The majority of the
conformance statement for DICONDE will be similar to DICOM. The exception being that the information objects listed in the
conformance statement should be the DICONDE specific information objects that the implementation supports.
4.6.2 As the DICONDE standard continues to evolve, data elements, modules, and information object definitions are added to the
family of DICONDE standard practices. As this occurs, it is likely that these additions may result in DICONDE files or objects
created using previous versions of the standard practices becoming non-conforming to the most recent standard practice. The
conformance of a DICONDE file or object needs to be determined relative to the versions of the standard practices used to create
the file or object.
4.6.3 To track the version of the DICONDE standard practice used to create a DICONDE file or object, the Software Versions
(0018, 1020) attribute is used to store a unique identifier. This unique identifier corresponds to the version of the DICONDE
standard practice used to create the file or object. For more information, see subsection 7.2.5 of this document.
4.7 Practice E3147 provides methods for determining if the practices defined in this and other DICONDE practices are
implemented correctly. It also provides methods for assuring that multiple DICONDE implementations can successfully
interoperate together.
5. Significance and Use
5.1 Personnel that are responsible for the transfer of NDE data between systems will use this standard. This practice will define
a set of NDE information object definitions that along with the DICOM standard will provide a standard means to organize image
data. Once conformance statements have been generated, the NDE image data may be displayed on any imaging/analysis device
that conforms to the standard. This process of developing conformance statements with both the NDE specific object definitions
and the DICOM accepted definitions, will provide a means to automatically and transparently communicate between compliant
equipment without loss of information.
NOTE 1—Knowledge and understanding of the existing DICOM standard will be required to generate conformance statements and thereby facilitate the
data transfer.
6. Information Object and Service-Object Pair Class Definitions
6.1 Information Object Definitions
6.1.1 Details of the DICOM Information Object Definitions can be found in the DICOM Standard Part 3, Annexes A and B.
6.1.2 DICONDE Information Object Definitions are found in the method-specific standard practices. practices (Practices E2663,
E2699, E2738, E2767, and E2934). For a list of current method-specific standard practices, refer to subsection 2.1 of this
document.
6.1.3 The Information Object Definition is composed of a table of Information Modules included in the IOD. This table includes
a usage for each module. Usage is used to specify whether an information module is Mandatory (M), Conditional (C), or User
Optional (U). The usage of the information module takes precedence over the type of the data element. For example, a data element
of type 1 in an information module whose usage is U need only be present with a value if the user chooses to include that
information module in the DICONDE file or object. If that information module is not included in the file or object that data element
is not required to be included with a value.
6.2 DICOM to DICONDE Information Object Definition
6.2.1 The DICOM standard specifies mandatory, conditional, and user optional information modules for each DICOM IOD. The
relationship between the IODs and modules is found in the DICOM Standard Part 3. The DICONDE standard will follow that
relationship except as noted.
6.2.2 The terminology associated with certain modules of the DICOM information objects must be changed for use in an industrial
E2339 − 21
context. For instance, industry deals with components not patients. In the industrial objects, the equivalent medical information
modules will be reused when possible. For example, a Component information module will be assigned to the Patient information
module.
6.2.3 In some cases, there will exist no equivalent medical information module for a required set of industrial data. When no
equivalent DICOM information module exists, an industrial specific data module will be created as part of that object.
6.3 Service-Object Pair (SOP) Class Definitions:
6.3.1 Details of the DICOM SOP Class Definitions can be found in the DICOM Standard, Part 4, Section 6.
6.4 DICOM to DICONDE SOP Class Definitions:
6.4.1 The DICOM standard defines Standard, Standard Extended, Specialized Extended and Private SOP Classes in Part 2, Section
3.11.
6.4.2 To maintain compatibility with standard DICOM devices, the DICONDE standard will be based on Standard Extended
DICOM SOP Classes as described in Part 2, Section 3.11.3 of the DICOM Standard except as noted below.
6.4.3 Some nondestructive testing methods do not have an equivalent medical imaging modality. An example of such a test method
is Eddy Current testing. For these test methods, the DICONDE standard will define DICONDE Standard SOP Classes instead of
using DICOM Standard Extended SOP Classes.
6.5 Conformance:
6.5.1 Since the DICONDE standard is based on Standard Extended DICOM SOP Classes, only DICOM devices with Level 2
(Full) conformance should be used in DICONDE applications. Level 2 (Full) conformance ensures that all Type 1, 2 and 3 as well
as Private attributes will be stored and may be accessed by the device. See DICOM Part 4, Section B.4 for more information.
6.5.2 Note that test data that use DICONDE Standard SOP Classes may not be accepted or displayed by many standard DICOM
image display and storage tools since these SOP classes are not used in medical applications.
6.6 For network communication, DICOM Standard PS 3, part 4, section C.6 defines both a Patient Root Query/Retrieve
Information Model and a Study Root Query/Retrieve Information Model. With specific regard to DICONDE, the Component ID
is not a central reference point as it is in the medical field, and due to the varied industries and NDE procedures, reconciling
evaluation data to a single field can be problematic. For example, Component Name variations could be overwritten because of
reconciliation against Component ID. As the Patient Root is specifically aimed at a reconciled master index around the Patient ID
(Component ID), it is therefore not included in the DICONDE standard. Non-inclusion of this model in the DICONDE standard
in no way breaks or prevents the implementation and use of that model.
7. DICONDE Information Modules
7.1 Information Module Definitions
7.1.1 Details of the DICOM Information Module Definitions can be found in the DICOM Standard Part 3, Annex C.
7.1.2 All data elements in the information modules must be described by an attribute name, a data element tag, a value
representation (VR), a value multiplicity (VM), and a data element type.
7.2 DICOM to DICONDE Information Module Definition
7.2.1 The terminology associated with certain elements of the DICOM information modules must be changed for use in an
industrial context. For instance, industry deals with partscomponents, not patients. The DICONDE standard defines industrial
information modules that are equivalent to those found in the DICOM standard. In the industrial modules, the equivalent medical
data elements will be reused when possible. For example, a component ID number or serial number will be assigned to the Patient
ID attribute.
E2339 − 21
7.2.2 In some cases, there will exist no equivalent medical data element for a required industrial data element. There is no
equivalent of Component Manufacturer in the current DICOM data model. When no equivalent DICOM data element exists, an
industrial specific data element will be created as part of that module.
7.2.3 When a logical correspondence exists, an existing DICOM data element,element with an associated NDE meaning
associated with them, will be used for industrial data. For example, the Patient Name data element (0010, 0010) is used to store
Component Name for NDE applications.
7.2.4 Some industrial data element tags are unique and do not duplicate any existing medical tags. These NDE data elements are
stored as DICOM Private Data Element Tags. Private data elements tags are defined in Part 5, Section 7.8 of the DICOM standard.
7.2.5 The version identifier of the DICONDE file will be stored in the Software Versions data element (0018, 1020) in the NDE
Equipment Module. The Software Versions data element is multi-valued. If additional software versions are stored in this data
element, the DICONDE version must be the first value stored in the data element. The current DICONDE version identifier is
“DICONDE15”.“DICONDE21”. No changes in capitalization or spacing is allowed in the DICONDE version identifier.
7.3 DICONDE Information Modules
7.3.1 The DICONDE practice contains the common modules that are needed for every technique. Any technique specific modules
for NDE will have information modules, attributes, and data elements identified in a technique specific practice.
7.3.2 Table 1 summarizes the current list of industrial modules and, if appropriate, the medical modules that they supersede.
7.4 Component Module
7.4.1 Table 2 specifies the attributes that describe components.
7.4.1.1 For information objects using the component module, Component Shape (0014, 0050) (0014,0050) is specified to use the
values in Table 3.
7.4.1.2 For information objects using the component module, Curvature Type (0014, 0052) (0014,0052) is specified to use the
following values:
