ASTM E2934-14(2018)

Standard Practice for Digital Imaging and Communication in Nondestructive Evaluation (DICONDE) for Eddy Current (EC) Test Methods

SIGNIFICANCE AND USE
5.1 Personnel that are responsible for the creation, transfer, and storage of eddy current NDE test results will use this standard. This practice defines a set of information modules that along with the Practice E2339 and the DICOM standard provides a standard means to organize eddy current test parameters and results. The eddy current examination results may be displayed or analyzed on any device that conforms to the standard. Personnel wishing to view any eddy current examination data stored according to Practice E2339 may use this document to help them decode and display the data contained in the DICONDE compliant inspection record.
SCOPE
1.1 This practice facilitates the interoperability of eddy current imaging and data acquisition equipment by specifying the image data transfer and archival storage in commonly accepted terms. This document is intended to be used in conjunction with Practice E2339 on Digital Imaging and Communication in Nondestructive Evaluation (DICONDE). Practice E2339 defines an industrial adaptation of 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 storage. The goal of Practice E2339, commonly referred to as DICONDE, is to provide a standard that facilitates the display and analysis of NDE results on any system conforming to the DICONDE standard. Toward that end, Practice E2339 provides a data dictionary and a set of information modules that are applicable to all NDE modalities. This practice supplements Practice E2339 by providing information object definitions, information modules and a data dictionary that are specific to eddy current test methods.  
1.2 This practice has been developed to overcome the issues that arise when analyzing or archiving data from eddy current test equipment using proprietary data transfer and storage methods. As digital technologies evolve, data must remain decipherable through the use of open, industry-wide methods for data transfer and archival storage. This practice defines a method where all the eddy current technique parameters and inspection data are communicated and stored in a standard manner regardless of changes in digital technology.  
1.3 This practice does not specify:  
1.3.1 A testing or validation procedure to assess an implementation's conformance to the standard,  
1.3.2 The implementation details of any features of the standard on a device claiming conformance, or  
1.3.3 The overall set of features and functions to be expected from a system implemented by integrating a group of devices each claiming DICONDE conformance.  
1.4 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 values stated in SI units 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 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 A fundamental principle of DICONDE is the use of standard definitions and attribute formats for data communication and
storage. This means all systems that are DICONDE compliant use a common data dictionary and common communication
protocols. To further standardization, the elements in the data dictionary are organized into common groups referred to as
information 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 requirements
for each individual modality (Computed Tomography, Digital Radiography, Computed Radiography, Ultrasonic, etc.). Additions
to the data dictionary and information modules are required to support the individual modalities. This practice contains the
additions to the DICONDE data dictionary and information modules necessary for eddy current inspection.
4.3 The highest organizational level in the DICONDE information model is the information object definition (IOD). The
information object definition is a collection of information modules necessary to represent a set of examination results from a
specific modality. This practice contains information object definitions necessary for eddy current inspection.
5. Significance and Use
5.1 Personnel that are responsible for the creation, transfer, and storage of eddy current NDE test results will use this standard.
This practice defines a set of information modules that along with the Practice E2339 and the DICOM standard provides a standard
means to organize eddy current test parameters and results. The eddy current examination results may be displayed or analyzed
on any device that conforms to the standard. Personnel wishing to view any eddy current examination data stored according to
Practice E2339 may use this document to help them decode and display the data contained in the DICONDE compliant inspection
record.
6. Information Object Definitions
6.1 Eddy Current Image IOD Description
6.1.1 The Eddy Current (EC) Image Information Object Definition specifies an image that has been created by an Eddy Current
imaging device for NDE purposes. The IOD definition is found in Table 1. Note that eddy current has no equivalent medical
imaging modality. While the IOD definition utilizes standard information modules from the DICOM standard there exists no EC
IOD within the DICOM standard.
6.1.2 Since there is no EC IOD within the DICOM standard the option of using a DICOM Standard Extended Service-Object
Pair (SOP) Class does not exist. A SOP Class Name and Unique Identifier (UID) have been provided to the EC IOD in Table 3.
Note that since this is not a DICOM SOP Class, many standard DICOM image display and storage tools may not accept these
images.

Definition of usage codes can be found in Part 3 Section A.1.3 of the DICOM standard.
6.2 Eddy Current Multi-Frame Image
6.2.1 The Eddy Current Multi-Frame (EC-MF) Image Information Object Definition specifies a multi-frame image that has been
created by an Eddy Current imaging device for NDE purposes. The IOD definition is found in Table 2. Note that eddy current
multi-frame has no equivalent medical imaging modality. While the IOD definition utilizes standard information modules from the
DICOM standard there exists no EC-MF IOD within the DICOM standard.
6.2.2 Since there is no EC-MF IOD within the DICOM standard the option of using a DICOM Standard Extended
Service-Object Pair (SOP) Class does not exist. A SOP Class Name and Unique Identifier (UID) have been provided to the EC-MF
IOD in Table 3. Note that since this is not a DICOM SOP Class, many standard DICOM image display and storage tools may not
accept these images.
7. Information Modules
7.1 Component Series Module
7.1.1 The Component Series Module for eddy current images will be as described in Practice E2339 Section 7, except as noted
below.
7.1.1.1 For eddy current images the Modality attribute (0008,0060) will have the value of EC.
7.2 NDE EC Image Module
7.2.1 Table 4 specifies the Attributes that describe NDE eddy current images.
7.2.1.1 For NDE EC Images, Samples per Pixel (0028,0002) is specified to use the following values for specified Photometric
Interpretations.

7.2.1.2 For NDE EC Images, Photometric Interpretation (0028,0004) is specified to use the following defined terms. See Part
3 Section C.7.6 of the DICOM standard for definitions of the terms:
