Abstract. In 2004, ASTM published the DICONDE (Digital Imaging and Communication in NDE) standard practice for the storage and communication of digital nondestructive evaluation (NDE) results. The current DICONDE practice (ASTM E2339-08) addresses only issues that apply to all NDE modalities. We will discuss our methodology for developing new Information Object Definitions for those NDT imaging modalities that have needs that are not currently addressed by the ASTM 2339-08 standard. We describe our definitions for ultrasound, digital radiography and computed tomography based on metadata in the ACR-NEMA DICOM standard with adaptations for industrial applications. After giving a brief overview of DICOM, we address several information entities required by ASTM industrial ultrasonic and radiography standards that have no comparable attributes in medical imaging. Several examples of attributes that present difficulties in using basic DICOM data structures will be identified (e.g., the spatial positioning of an object in the field of view or the number of rads generated by a linear accelerator source). Solutions to these problems will be proposed. We will also discuss the advantages and disadvantages of creating a new storage class for nondestructive testing. Lastly, we will discuss the use of DICONDE conformance statements, which are based on the DICOM standard, in evaluating an imaging system’s compliance to DICONDE and its interoperability with other systems that claim DICONDE compliance. This article was presented at the BINDT 2008.

DICONDE – Customer Benefits
• Avoid legacy data conversion costs when upgrading inspection systems (or useless data!)
• Archive data from multiple inspection equipment vendors in one system
• Support for data format beyond a single equipment vendor –“best of breed”
• Allows customers to review past inspection data with future software tools
