ASTM-E2767 › Standard Practice for Digital Imaging and Communication in Nondestructive Evaluation (DICONDE) for X-ray Computed Tomography (CT) Test Methods
Show Complete Document History
The following bibliographic material is provided to assist you with your purchasing decision:
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 on Digital Imaging and Communication in Nondestructive Evaluation (DICONDE). Practice 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 , 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 provides a data dictionary and a set of information modules that are applicable to all NDE modalities. This practice supplements Practice 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.
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 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 may use this document to help them decode and display the data contained in the DICONDE-compliant inspection record.
