Standardized Electronic File Format Will Allow Global Viewing of Nondestructive Test Image Data

Easily accessible, clear computer images of parts subjected to nondestructive testing render improved components for airplanes, medical devices, and other products. The development of a standardized electronic file format—that allows worldwide viewing of digitally-transmitted nondestructive test results—is the goal of a new subcommittee added to ASTM Committee E07 on Nondestructive Testing (NDT) in June.

Leaders of the film, electronic imaging, aerospace, steel, shipbuilding, and research industries have sent their foremost application engineers to participate on new ASTM Subcommittee E07.11 on Digital Imaging and Communication in Nondestructive Evaluation (DICONDE). Thirty-one individuals have joined hands to create the standardized format for proposed implementation at their corporations, representing producers, users, and testers.

In their scope, the subcommittee stated that the proposed DICONDE standardized file format will be based on the universally-adopted medical standard DICOM, allowing worldwide review by NDT methodologies capable of generating images in an electronic format. It will be updated according to the bylaws of Committee E07 and will:

• Be DICOM 3.0 compatible;

• Support standardization of multiple data fields; and

• Allow international passage of digital image data from source to storage, acquisition to archive.

Heading new Subcommittee E07.11 are chairman Christopher Voelker, Boeing McDonnell Aircraft and Missile Systems (e-mail: christopher.y.voelker@ @boeing.com), vice-chairman Regi Serluppens, AGFA (e-mail: regi.serluppens. rs@belgium.agfa.com), and secretary Gerald Nightingale, GE Aircraft Engines (ben.nightingale@ae.ge.com).

New subcommittee task groups and their chairpersons are:

• DICONDE Standard Guide Task Group, chaired by Voelker;

• DICONDE Standard Practice TG, chaired by Claudia Kropas-Hughes, Wright Patterson Air Force Base;

• Computed Radiography TG, chaired by Serluppens;

• Computed Tomography TG, chaired by Kropas-Hughes;

• Digital Radiology TG, chaired by Larry Sawyer, Fuji;

• Ultrasonic Testing TG, chaired by Eugene Chemma, Bethlehem Steel;

• Eddy Current TG, chaired by Cuong Le, Andrew NDT; and

• Infrared Thermography TG, chaired by Bruce Rubadeux, Thermal Wave Imaging.

Objectives of the new subcommittee include the implementation of validation tools at the Fuji and AGFA Web sites; inclusion of GPS (global positioning system) as an image file attribute; implementation of the OFFIS (Oldenburger Forschungs - und Entwicklunginstitut für Informatik - Werkzeuge und - Systeme) source code to further develop the database engine; and extending the data dictionary tables to include all general NDE systems that use digital imaging.

To participate in these activities or for further technical information, contact Christopher Voelker, Boeing McDonnell Aircraft and Missile Systems, MC S029-1270, PO Box 516, St. Louis, MO 63166-0516 (314/233-5971; fax: 314/232-1253). Subcommittee E07.11 meets Sunday, Jan. 21 during the Jan. 21-25 meetings of Committee E07 in Plantation, Fla.
