1、Designation: E1475 02 (Reapproved 2008)E1475 13Standard Guide forData Fields for Computerized Transfer of DigitalRadiological Examination Data1This standard is issued under the fixed designation E1475; the number immediately following the designation indicates the year oforiginal adoption or, in the
2、 case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This guide provides a listing and description of the fields that are recommended for in
3、clusion in a digital radiologicalexamination data base to facilitate the transfer of such data.This guide sets guidelines for the format of data fields for computerizedtransfer of digital image files obtained from radiographic, radioscopic, computed radiographic, or other radiological examinationsys
4、tems.The field listing includes those fields regarded as necessary for inclusion in the data base: (1) regardless of the radiologicalexamination method (as indicated by Footnote C in Table 1), (2) for radioscopic examination (as indicated by Footnote EF in Table1), and (3) for radiographic examinati
5、on (as indicated by Footnote D in Table 1). In addition, other optional fields are listed as areminder of the types of information that may be useful for additional understanding of the data or applicable to a limited numberof applications.1.2 It is recognized that organizations may have in place an
6、 internal format for the storage and retrieval of radiologicalexamination data. This guide should not impede the use of such formats since it is probable that the necessary fields are alreadyincluded in such internal data bases, or that the few additions can easily be made. The numerical listing and
7、 its order indicated inthis guide is only for convenience; the specific numbers and their order carry no inherent significance and are not part of the datafile.1.3 Current users of Guide E1475 do not have to change their software. First time users should use the XML structure of TableA1.1 for their
8、data.1.4 The types of radiological examination systems that appear useful in relation to this guide include radioscopic systems asdescribed in Guide E1000, Practices E1255, E1411, E2597, E2698 and E2033E2737, and radiographic systems as described inGuide E94 and Practices E748, E1742and, E1742E2033,
9、 E2445, and E2446. Many of the terms used are defined in TerminologyE1316.1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.6 This standard does not purport to address all of the safety concerns, if any, associated with it
10、s use. It is the responsibilityof the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatorylimitations prior to use.2.
