(Practice)Standard Practice for Digital Imaging and Communication in Nondestructive Evaluation (DICONDE) for X-ray Computed Tomography (CT) Test Methods
Standard Practice for Digital Imaging and Communication in Nondestructive Evaluation (DICONDE) for X-ray Computed Tomography (CT) Test Methods
SIGNIFICANCE AND USE
5.1 Personnel that are responsible for the creation, transfer, and storage of X-ray tomographic NDE data will use this standard. This practice defines a set of information modules that along with Practice E2339 and the DICOM standard provide a standard means to organize X-ray tomography test parameters and results. The X-ray CT test results may be displayed and analyzed on any device that conforms to this standard. Personnel wishing to view any tomographic inspection 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 X-ray computed tomography (CT) imaging equipment by specifying image data transfer and archival storage methods 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 test 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 X-ray CT test methods.
1.2 This practice has been developed to overcome the issues that arise when analyzing or archiving data from tomographic 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 X-ray CT technique parameters and test results 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.
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.

Practice E2339, commonly referred to as DICONDE, is to provide a standard that facilitates the display and analysis of NDE test
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

3. Terminology
3.1 Definitions:
3.1.1 Nondestructive evaluation terms used in this practice can be found in Standard Terminology for Nondestructive
Examinations, E1316.
3.1.2 Computed Tomography terms used in this practice can be found in Standard Guide for Computed Tomography (CT)
Imaging, E1441.
3.1.3 DICONDE terms used in this practice are defined in Practice E2339.
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 (CT, DR, CR, UT, 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 X-ray CT inspection.
4.3 The highest organizational level in the DICONDE information model is the information object definition (IOD). An
information object definition is a collection of the information modules necessary to represent a set of test results from a specific
modality. This practice contains information object definitions for X-ray CT inspection.
5. Significance and Use
5.1 Personnel that are responsible for the creation, transfer, and storage of X-ray tomographic NDE data will use this standard.
This practice defines a set of information modules that along with Practice E2339 and the DICOM standard provide a standard
means to organize X-ray tomography test parameters and results. The X-ray CT test results may be displayed and analyzed on any
device that conforms to this standard. Personnel wishing to view any tomographic inspection 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 X-ray CT Image IOD Description:
6.1.1 The X-ray CT Image Information Object Definition specifies an image that has been created by an X-ray CT imaging
device for NDE purposes. To avoid duplication of relevant material from the DICOM standard, the IOD definition will follow that

and must be used in conjunction with Part 3, Section A.3 of the DICOM standard to have a complete definition of the DICONDE
CT information object. In addition to the DICONDE information modules specified in Practice E2339 and this standard, the
DICONDE CT IOD utilizes additional DICOM standard information modules as noted in Table 1.
6.1.2 This IOD will use the Service-Object Pair (SOP) Classes for the CT IOD as defined in Part 4, Section B.5 of the DICOM
standard.
6.2 X-ray CT Multi-Frame Image IOD Description:
6.2.1 The X-ray CT Multi-Frame (CT-MF) Image Information Object Definition specifies a multi-frame image that has been
created by an X-ray CT imaging device for NDE purposes. To avoid duplication of relevant material from the DICOM standard,
the IOD definition will follow that for Enhanced CT Images found in Part 3, Section A.38 of the DICOM standard except as noted
below in Table 2. Table 2 is not stand-alone and must be used in conjunction with Part 3, Section A.38 of the DICOM standard
to have a complete definition of the DICONDE CT-MF information object.

KVP (0018,0060) DS 1 2 Peak kilo voltage output of the X-ray generator used.
Acquisition Number (0020,0012) IS 1 2 A number identifying the single continuous gathering of data over a
period of time which resulted in this image.
Scan Options (0018,0022) CS 1-n 3 Parameters of the scanning sequence.
Data Collection Diameter (0018,0090) DS 1 3 The diameter in mm of the region over which data were collected.
Reconstruction Diameter (0018,1100) DS 1 3 Diameter in mm of the region from within which data were used in
creating the reconstruction of the image. Data may exist outside of
this portion of the region and portions of the component may exist
outside this region.
Distance Source to (0018,1110) DS 1 3 Distance in mm from source to detector center.
Detector
Distance Source to (0018,1111) DS 1 3 Distance in mm from source to isocenter (center of field of view).
Component
