Standard Guide for Data Fields for Computerized Transfer of Digital Ultrasonic Testing Data (Withdrawn 2013)

SIGNIFICANCE AND USE
The primary use of this guide is to provide a standardized approach for the data file to be used for the transfer of digital ultrasonic data from one user to another where the two users are working with dissimilar ultrasonic systems. This guide describes the contents, both required and optional, for an intermediate data file that can be created from the native format of the ultrasonic system on which the data was collected and that can be converted into the native format of the receiving ultrasonic or data analysis system. The development of translator software to accomplish these data format conversions is being addressed under a separate effort; this will include specific items needed for the data transfer, for example, language used, memory requirements and intermediate specification, including detailed data formats and structures. Ths guide will also be useful in the archival storage and retrieval of ultrasonic data as either a data format specifier or as a guide to the data elements that should be included in the archival file.
Although the recommended field listing includes more than 120 items, only about one third of those are regarded as essential and marked with Footnote C in Table 1. Fields so marked must be addressed in the data base. The other recommended fields provide additional information that a user will find helpful in understanding the ultrasonic examination result. These header field items will, in most cases, make up only a very small part of an ultrasonic examination file. The actual stream of ultrasonic data that make up the image will take up the largest part of the data base. Since an ultrasonic image file will normally be large, the concept of data compression will be considered in many cases. Compressed data should be noted, along with a description of the compression method, as indicated in Field No. 122.
This guide describes the structure of a data file for all of the ultrasonic information collected in a single scan. Some systems re...
SCOPE
1.1 This guide provides a listing and description of the fields that are recommended for inclusion in a digital ultrasonic examination data base to facilitate the transfer of such data. This guide is prepared for use particularly with digital image data obtained from ultrasonic scanning systems. The field listing includes those fields regarded as necessary for inclusion in the data base (as indicated by Footnote C in Table 1); these fields, so marked, are regarded as the minimum information necessary for a transfer recipient to understand the data. In addition, other optional fields are listed as a remainder 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 ultrasonic examination 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 be made. The numerical listing indicated in this guide is only for convenience; the specific numbers carry no inherent significance and are not a part of the data file.
1.3 The types of ultrasonic examination systems that appear useful in relation to this guide include those described in Practices E 114, E 214 and E 1001. Many of the terms used are defined in Terminology E 1013 and E 1316. The search unit parameters used in this guide follow from those used in Guide E 1065.
1.4 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 and health practices and determine the applicability of regulatory limitations prior to use.
