ASTM E1475 : 97

1.1 This guide provides a listing and description of the fields that are recommended for inclusion in a digital radiological test data base to facilitate the transfer of such data. The guide is prepared for use particularly with digital images obtained from radiographic or radioscopic examination systems. Nevertheless, this document provides guidance for data bases for other radiological examinations. The field listing includes those fields regarded as necessary for inclusion in the data base: ( ) regardless of the radiological examination method (as indicated by Footnote C in Table 1), ( ) for radioscopic examination (as indicated by Footnote E in Table 1), and ( ) for radiographic examination (as indicated by Footnote D in Table 1). In addition, other optional fields are listed as a reminder of the types of information that may be useful for additional understanding of the data or applicable to a limited number of applications.

1.2 It is recognized that organizations may have in place an internal format for the storage and retrieval of radiological test data. This guide should not impede the use of such formats since it is probable that the necessary fields are already included in such internal data bases, or that the few additions can easily be made. The numerical listing indicated in this guide is only for convenience; the specific numbers carry no inherent significance and are not part of the data file.

1.3 The types of radiological test systems that appear useful in relation to this guide include radioscopic systems as described in Guide E1000, Practices E1255 and E1411, and radiographic systems as described in Guide E94 and Practices E748. Many of the terms used are defined in Terminologies E1013 and E1316.

1.4 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
