1. Scope*
1.1 This practice facilitatescovers the interoperability of digital X-ray imaging equipment using Digital Detector Arrays (DDA)
as described in Practice E2698 by specifying image data transfer and archival methods in commonly accepted terms. A separate
practice, Practice E2738, addresses this topic for digital X-ray imaging equipment using Computed Radiography (CR). 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 StandardsDICOM NEMA PS3 Publication
titled Digital Imaging and Communications in Medicine ⁄ ISO 12052 (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 digital X-ray test methods.
1.2 This practice has been developed to overcome the issues that arise when analyzing or archiving data from digital X-ray 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 digital X-ray 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 Units—Although this practice contains no values that require units, it does describe methods to store and communicate data
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).

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 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.

3. Terminology
3.1 Definitions:
3.1.1 Nondestructive evaluation terms used in this practice can be found in Terminology 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 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 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, DDA, 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 digital X-ray inspection using Digital Detector Arrays.
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 digital X-ray inspection using Digital Detector Arrays.

7.1.1.2 For NDE DX Images, Detector Configuration (0018,7005) is specified to use the following defined terms.
AREA
LINEAR
7.1.1.3 If Pixel Spacing (0028,0030) is present and the image has not been calibrated to correct for the effect of geometric
magnification, the values of this attribute shall be the same as in Imager Pixel Spacing (0018,1164), if either of those attributes
are present.
(1) If Pixel Spacing (0028,0030) is present and the values are different from those in Imager Pixel Spacing (0018,1164), then
the image has been corrected for known or assumed geometric magnification or calibrated with respect to some object of known
size at known depth within the component.
(2) If Pixel Spacing Calibration Type (0028,0A02) and Imager Pixel Spacing (0018,1164) and Nominal Scanned Pixel Spacing
(0018,2010) are absent, then it cannot be determined whether or not correction or calibration have been performed.
7.1.1.4 For NDE DX Images, Pixel Spacing Calibration Type (0028,0A02) is specified to use the following defined terms.
GEOMETRY
The Pixel Spacing (0028,0030) values account for assumed or known geometric magnification effects and correspond to some unspecified depth within the component; the Pixel
Spacing (0028,0030) values may thus be used for measurements of objects located close to the central ray and at the same depth.
FIDUCIAL
The Pixel Spacing (0028,0030) values have been calibrated by the operator or image processing software by measurement of an object (fiducial) that is visible in the pixel data and
is of known size and is located close to the central ray; the Pixel Spacing (0028,0030) values may thus be used for measurements of objects located close to the central ray and
located at the same depth within the component as the fiducial.
7.1.1.5 Note for Pixel Spacing Calibration Description (0028,0A04)—In the case of correction, the text might include description
of the assumptions made about the component and geometry and depth within the component. In the case of calibration, the text
might include a description of the fiducial and where it is located. Though it is not required, the Device Module (see Part 3, Section
