1. Scope | ||||||||||||
1.1 This reference radiograph covers a series of test targets suitable for evaluating, quantifying, and documenting performance parameters of the radiographic digitization process or the electronic image reconstruction process, or both. This reference radiograph can be used for visual and electronic analysis of digitization systems. 1.2 This reference radiograph provides a series of test targets to provide a vehicle for the evaluation of spatial resolution, density contrast sensitivity, dynamic range, and spatial linearity as well as other aspects of a digitization system. The test targets are suitable for evaluating a digitization system with a spatial resolution down to ∼1/1000 in. (25 micrometres (μm)), a density contrast sensitivity down to 0.02 optical density (OD), a density range of 0.5 to 4.5 OD, and a film size capacity of 14 in. (355 mm) wide by 17 in. (431 mm) long. 1.3 From time to time, there may be minor changes to the process for manufacturing of the reference adjunct film. These changes could include changes in the films or processing chemistry used, text designation on the film, etc.; however, in all cases, these changes are reviewed by the Illustration Monitoring Subcommittee to ensure that there are no changes to the functional use of the reference image. Therefore, the adjunct reference films remain valid for use with this standard regardless of the date of production or the revision level of the text standard. 1.4 The values stated in inch-pound units are to be regarded as the standard, with the exception of the spatial resolution targets (6.2 and 6.7) which are stated in SI units. 1.5 This standard does not purport to address 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. |
